Executive Summary An Interconnection Facilities Study (IFS) has been performed to determine the Manitoba Hydro Interconnection Facilities and Interconnection System and Network Upgrades necessary to connect 99 MW of wind generation near the town of Elie, Manitoba from the point designated for the location of the generation facility. Two options for interconnection were considered. Option A: the 99 MW Elie wind farm would tap 230 kV line D12C approximately 30 km from Dorsey and sectionalize the line with a three-breaker ring bus. Option B: the 99 MW Elie wind farm would advance the 30 km Dorsey-Elie section of a planned new 230 kV Dorsey-Portage line. The new Dorsey-Portage line would be tapped at Elie via a single 230 kV breaker, creating a three-terminal line when the remaining Elie-Portage line is built. AC contingency analysis was performed for N-1 and N-2 contingencies during system intact conditions, and N-1 contingencies during critical 230 kV prior outages. There were no N-1 thermal overloads impacted by the Elie wind farm that required further investigation. Therefore no Network Upgrades or Interconnection System Upgrades are required. The Manitoba Hydro Transmission System Interconnection Requirements (TSIR) [1] state that the Generator must provide reactive supply that is able to control the voltage level at the Elie 230 kV bus by adjusting the Machine’s power factor between a minimum of 0.95 overexcited and 0.95 underexcited at the generator intermediate bus with a minimum response time of 15 seconds. The Turbine A wind turbines would need additional VAR support in the form of 3x10 MVAr switched capacitors plus an 8 MVAr STATCOM on the 34.5 kV bus. The Turbine B wind turbines have a reactive supply range from 0.9 lagging to 0.95 leading and do not require any additional equipment. In order for the wind turbines to remain connected during transient undervoltages, a wind turbine with fault ride-through capability must be installed. Both the Turbine A turbine and Turbine B turbine (with Turbine B Low Voltage Ride-through option II) have adequate fault ride-through capability. It should be noted that a 230-34.5 kV transformer with a minimum 7.5% impedance is needed to ensure the voltage at the generator buses remain above 0.15 pu during a solid Elie 230 kV fault in order to ride through the fault. In order to remain connected during the worst-case transient overvoltages and undervoltages, to meet the Manitoba Hydro transient undervoltage criteria, and also to ensure acceptable steady state operating voltages at the generator bus, the Turbine A turbines must install a 230-34.5 kV transformer with an on-load tap changer (OLTC), capable of controlling the 34.5 kV bus voltage to 1.0 pu + 0.02 pu for Option A and to 0.97 + 0.02 pu for Option B. The Turbine B turbines are able to ride through the worst-case transient overvoltages and undervoltages without any extra equipment. During critical 230 kV outages, the generator has opted for curtailment rather than paying for additional line upgrades. For Option A, this could result in wind farm curtailment for a prior outage of 230 kV line G37C or D54C when no Brandon generation is on-line to

iii

prevent potential overloading of 230 kV line D12C following the loss of line D54C or G37C respectively. Otherwise, Brandon generation could be increased to off-load line D12C in this situation. The Turbine A turbines and the Turbine B turbines do not require any curtailment of wind farm power output for transient stability reasons. The overfrequency and underfrequency capabilities of the Turbine A and Turbine B wind turbines meet the Manitoba Hydro connection standards. A detailed cost estimate of the Manitoba Hydro Interconnection Facilities necessary to connect a 99 MW Elie wind farm via Option A and Option B were calculated. These total costs were estimated to be $13,009,000 for Option A and $12,681,500 for Option B. A detailed project schedule was also created, with a preliminary estimated time to in-service date of 2.5 years after the IOA has been finalized. The final project schedule will be inserted into Appendix D when completed.

1.0 Introduction 1.1 Background Information This report documents the results of an Interconnection Facility Study for a 99 MW Elie wind farm, located approximately 30 km west along 230 kV line D12C from the Dorsey 230 kV station. The Manitoba Hydro Interconnection Facilities will be determined for a wind farm size of 99 MW. The preliminary estimated time to in-service date is 2.5 years after the IOA has been finalized. The final project schedule will be inserted into Appendix D when completed. Two options for interconnection were considered. Option A: the 99 MW Elie wind farm would tap 230 kV line D12C approximately 30 km from Dorsey and sectionalize the line with a three-breaker ring bus. A direct connection to the new Elie 230 kV station bus will be made via a 1.0 km 230 kV line. Option B: the 99 MW Elie wind farm would advance the 30 km Dorsey-Elie section of the planned 230 kV Dorsey-Portage line. The planned Dorsey-Portage line would be tapped at Elie via a single 230 kV breaker, creating a three-terminal line. Appendix B provides single line diagrams of the major Manitoba Hydro Interconnection Facilities required to connect the wind farm via both options. Manitoba Hydro Interconnection Facilities cost estimates for both options are provided in Section 11.0. The assumptions behind the cost estimates are provided in Appendix A. 1.2 Objectives The Interconnection Facilities Study objectives are to:

• address the system reliability limitations • determine a good faith cost estimate of all the interconnection facilities • determine a good faith construction schedule estimate • determine special protection requirements (e.g. breaker fail, generator cross trip) • determine communication requirements • satisfy any requirements of the Regional Transmission Authority

1.3 MH Technical Requirements for Generator Interconnection Please refer to Appendix C for additional technical requirements not discussed in the body of the report.

2.0 Interconnection System and Network Upgrades There are two types of Interconnection Services available:

1. Energy Resource Interconnection Service (ERIS) As stated in the Manitoba Hydro Open Access Interconnection Tariff (OAIT), “ERIS allows the Generator to connect the Facility to the System and be eligible to deliver the Facility’s output using the existing firm or non-firm capacity of the Transmission System on an “as available” basis. ERIS does not in and of itself convey any right to deliver electricity to any specific customer or Point of Delivery.” ERIS requires Interconnection Facilities and Interconnection System Upgrades, but not Network Upgrades.

2. Network Resource Interconnection Service (NRIS) As stated in the Manitoba Hydro Open Access Interconnection Tariff (OAIT), “NRIS allows the Generator’s Facility to be designated as a Network Resource, up to the Facility’s full output, on the same basis as existing Network Resources interconnected to Manitoba Hydro’s System. NRIS in and of itself does not convey any right to deliver electricity to any specific customer or Point of Delivery.” NRIS requires Interconnection Facilities, Interconnection System Upgrades and Network Upgrades.

Interconnection System Upgrades are the minimum necessary upgrades required to interconnect to the MH system and meet reliability criteria. A redispatch to the nearest existing Manitoba Hydro network resource is used as a test for Interconnection System Upgrades. For Elie, the nearest MH network resource is Dorsey. Where a facility is overloaded, dynamic line rating equipment could be installed to allow the operators to send a timely MW curtailment level to the plant. Network Upgrades are the upgrades required when the Manitoba Hydro Transmission System is studied at peak load, and other load levels deemed appropriate by Manitoba Hydro, under a variety of severely stressed conditions, to determine whether, with the Facility at full output, the aggregate of generation in Manitoba can be delivered to the aggregate load on the transmission system, consistent with Manitoba Hydro’s reliability criteria and procedures. In other words, it is necessary to be able to redispatch to all generators and load without requiring pre-contingency curtailment or violating post-contingency voltage and loading criteria. A generation crosstrip scheme may be considered as an alternative to new lines or reconductoring if the special protection system (SPS) is made fully redundant and the crosstrip amount is less than Manitoba Hydro’s operating reserves. Interconnection System Upgrades and Network Upgrades are separately identified. The Generator has requested that the 99 MW wind farm be considered a Manitoba Hydro network resource. As a network resource, the impacts of scheduling to generation within Manitoba were evaluated.

2.1 Steady State Analysis 2.1.1 Study Power Flow Models Steady state post-disturbance analysis was performed using the following 2004 series MAPP base case loadflows: A. 2009 summer peak – Existing firm generation plus queued generation at Pine Falls (5

MW), Great Falls (4 MW), Brandon (122 MW), and Kelsey (33 MW). B. 2014 summer peak – Existing firm generation plus queued generation noted above

plus Wuskwatim (200 MW) and associated transmission (Birchtree-Wuskwatim, Wuskwatim-Herblet Lake, Herblet Lake-Ralls Is., Dauphin-Neepawa).

Sensitivity analysis to Manitoba Hydro Export (MHEX) and North Dakota Export (NDEX) was performed. Four combinations of MHEX and NDEX were studied for both of the above 2009 and 2014 base cases: a. MHEX = 2175, NDEX = 1950 b. MHEX = 2175, NDEX = 300 c. MHEX = -900, NDEX = 1950 d. MHEX = -900, NDEX = 300 Sensitivity analysis to Brandon and Selkirk generation, as well as Lena wind generation, was also performed for the worst cases. The generation level in the MHEX 2175 MW summer peak cases were adjusted to the maximum accredited level less 55 MW to meet Manitoba’s regulating reserve requirements. MH is delivering firm and non-firm power sales on the tie lines as well as the MAPP reserve obligation. According to the position of Pembina Hills in the MH generator interconnection queue, the following future generation was included in the analysis;

• Brandon – 122 MW • Pine Falls – 6 MW • Kelsey – 33 MW • St. Leon Wind – 99 MW • Pembina Hills Wind – 99 MW

Table 1 summarizes the output from each generator in the maximum generation case at maximum Manitoba-US export of 2175 MW, and also at the maximum Manitoba-US import of 900 MW. The associated transmission upgrades for the queued generation are included in the analysis.

within Manitoba including tie lines. • N-2 contingencies for all 110 kV and above double-circuit outages in Manitoba and

breaker fail outages approximately two buses back from the Elie station (i.e. at Dorsey, Glenboro and Letellier)

Prior Outages (including D12C Dorsey-Elie, D12C Elie-Cornwallis, D14S, S53G, S60L, Y51L, G37C, D12C, D54C, C28R): • N-1 contingencies for all transmission lines and transformers 110 kV and above

within Manitoba including tie lines. System Intact analysis was assessed with Pembina Hills wind generation scheduled to each of the following sinks:

1. Grand Rapids generation (AGC plant) 2. Dorsey DC generation (AGC plant)

5

Prior Outage analysis was assessed with Pembina Hills wind generation scheduled to the following sink:

1. Dorsey DC generation (AGC plant) Facilities identified in the post-disturbance analysis were flagged if loading exceeded 100% and the system intact power flow or contingency power flow resulted in a power transfer distribution factor (PTDF) or an outage transfer distribution factor (OTDF) greater than 2%, respectively. Branch loadings were monitored using Rate A for normal conditions and Rate C following a contingency. Bus voltages lower than 0.90 pu were flagged. Mitigation is required for overloads in which the wind generation has a PTDF greater than or equal to 5% or an OTDF greater than or equal to 3% [8]-[12]. 2.2 Planning Criteria – Transmission Line Overloads Manitoba Hydro thermal loading criteria does not allow short-term overload for single contingency (category B) events. A short-term overload of up to 115% may be allowed for multiple contingency events (Category C such as double circuit common tower outages) on a case-by-case basis. If a short-term overload rating is applied, it is necessary to be able to reduce the loading to within the steady state thermal rating within 30 minutes of the overload occurrence. If the overloaded segment of a transmission line is station equipment rather than the line conductor, the overload capability for that piece of equipment will be individually assessed. Transformers are considered to have a 30-minute 119% Rate A summer overload rating. 2.3 Mitigation for Reliability Limitations Several thermal overloads were identified through AC contingency analysis that required detailed investigation. N-1 and N-2 contingencies were studied for system intact conditions. N-1 contingencies were also studied for critical 230 kV prior outages. The following sections provide details on the worst-case overloads for which the wind generator ODTF is 3% or greater. These overloads require mitigation. For information purposes, please refer to Appendix F for a list of all thermal overloads with PTDFs and OTDFs greater than or equal to 2%. Voltage violation impacts of 1% or greater are also listed. 2.3.1 System Intact: N-1 Contingencies There are no impacted overloads for which the Generator is responsible to provide mitigation for either connection Options A or B.

Appropriate mitigation action will be taken once the assessment is complete. For now, the BE3 overloads are being accepted. There are also plans to upgrade line BE3 to an approximate rating of 120.8 MVA summer and 157.8 MVA winter, which will be sufficient to mitigate these overloads. 2.3.3 Critical 230 kV Prior Outages: N-1 Contingencies For overloads that are impacted by the wind generation during prior outage conditions, the Generator has requested to be curtailed as necessary to prevent the overload from occurring, rather than implementing line/equipment upgrades. Critical 230 kV outages studied included lines D14S from Dorsey to St. Leon, S53G from St. Leon to Glenboro, S60L from St. Leon to Letellier, Y51L from Laverendrye to Letellier, G37C from Glenboro to Cornwallis, D12C from Dorsey to Elie, D12C from Elie to Cornwallis, D54C from Dorsey to Neepawa to Cornwallis, and C28R from Cornwallis to Reston. For a complete list of prior outage overloads impacted by a minimum of 2%, please refer to Appendix F. Table 2 lists the worst-case prior outage contingency overloads that have a minimum PTDF of 2%.

There is one increase to an existing overload for Connection Option A only. The impact is to the section of 230 kV line D12C from Elie wind to Portage South. The overload is a base case issue that occurs during low Brandon generation and at low NDEX during a prior outage of 230 kV line G37C or D54C. An increase in Brandon generation or decrease in Elie wind generation could be used to off-load line D12C. 2.3.4 Steady State Voltage Violations There were no steady state voltage violation impacts greater than 1% during system intact conditions.

2.4 Summary of Equipment Upgrades and Associated Costs The Elie 99 MW wind connection does not require any Network Upgrades or Interconnection System Upgrades.

3.0 Constrained Interface Analysis The Elie IES [5] performed constrained interface analysis for up to 99 MW of wind generation at Elie and demonstrated that there were no impacts greater than 3%. Therefore, additional studies are not required for the IFS.

4.0 Wind Turbine Models Two types of wind turbine models were tested during transient stability analysis: 1) Turbine A 1.65 MW, 60 Hz, with additional reactive power support in the form of:

- 4x10 MVAr, 34.5 kV switched capacitors - 3x10 MVAr, 34.5 kV switched capacitors, plus 1x8 MVAr D-STATCOM

2) Turbine B, 1.5 MW, 60 HZ, doubly-fed induction generator 4.1 Turbine A 1.65 MW 60 Hz The Turbine A wind turbines are the fixed-speed type consisting of a directly grid-coupled single cage induction generator. They come equipped with 49 MVAr of power factor correction capacitors located at the 600 V generator bus. The generator absorbs 42.1 MVAr at rated output. In PSS/E, the wind farm is represented as one aggregate generator, operating at 600 V. The aggregate generator is stepped up to 34.5 kV via a 108 MVA transformer of 5.56% impedance. The 10 MVAr switched capacitors are modeled at the 34.5 kV bus. The 34.5 kV collector system is stepped up to the 230 kV connection voltage via a 100/133/167 MVA transformer of 8.5% impedance. For Option A, a 1.0 km 230 kV transmission line connects the Elie wind farm to the new 230 kV Elie bus tapping D12C. For Option B, a 30 km 230 kV transmission line connects the Elie wind farm to the Dorsey 230 kV bus. An IPLAN is used to add the wind farm to the PSS/E large system model. Detailed PSS/E user models representing Turbine A are used to perform the stability analysis. The 8 MVAr STATCOM model data was provided by American Superconductor, and used the PSS/E library model CDSMS1. 4.2 Turbine B 60 Hz The Turbine B wind turbines are the variable-speed type consisting of a doubly-fed wound rotor induction generator. They are capable of fast voltage control over a power factor operation range of 0.95 overexcited to 0.9 underexcited. In PSS/E, the wind farm is represented as one aggregate generator, operating at 575 V. The aggregate generator is stepped up to 34.5 kV via a 115.5 MVA transformer of 5.0% impedance. The 34.5 kV collector system is stepped up to the 230 kV connection voltage via a 100/133/167 MVA transformer of 8.5% impedance. For Option A, a 1.0 km 230 kV transmission line connects the Elie wind farm to the new 230 kV Elie bus tapping D12C. For Option B, a 30 km 230 kV transmission line connects the Elie wind farm to the Dorsey 230 kV bus.

10

An IPLAN is used to add the wind farm to the PSS/E large system model. Detailed PSS/E user models representing Turbine B are used to perform the stability analysis. 4.3 Important Note regarding Transformer Impedance It should be noted that the 230-34.5 kV transformer was modeled with an impedance of 8.5% on a 100 MVA base. The impedance between the low voltage wind generator buses and the high voltage interconnection point plays an important role in the actual voltages seen at the low voltage wind generator buses, which in turn is the input to many protections. It is possible that if the impedance between the two points is significantly lower than or higher than what was modeled, overvoltages and/or undervoltages as seen at the generator bus will be more extreme, possibly causing the wind turbines to trip out when not expected, or for local voltage stability concerns to arise. If a 230-34.5 kV transformer with an impedance outside of the 7.5% to 9.5% range is planned to be used, it may be necessary to re-run several of the worst stability cases to ensure that the wind farm will still meet all of the Manitoba Hydro connection requirements in terms of riding through disturbances and respecting the transient undervoltage criteria. Update: The generator has indicated the actual 230-34.5 kV transformer impedance will be closer to 12% on a 100 MVA base (or 8.5% on a 70 MVA base). The worst-case system intact transient stability cases were re-run. The effect of a larger transformer impedance is a slightly less damped response to fault recovery and slightly higher transient overvoltages. For the D12C tap Option A connection, these system intact cases with the higher transformer impedance are not acceptable. The wind farm will trip due to overvoltage for loss of D602F with DC reduction (nbz fault), and local voltage collapse occurred for a three-phase fault on the Dorsey-Elie section of D12C. Therefore, the higher transformer impedance would require 2x8 MVAr STATCOMs and 2x10 MVAr switched capacitors instead of 1x8 MVAr STATCOM and 3x10 MVAr switched capacitors as discussed in the report. Prior outage curtailments could also be impacted, however this will be analyzed at a later date during Operating Studies. For the radial Dorsey-Elie Option B connection, these system intact cases with the higher transformer impedance are acceptable and require no additional facilities. Prior outage curtailments could be impacted, however this will be analyzed at a later date during Operating Studies.

5.0 Frequency, Voltage and Reactive Power Requirements Section 5 describes the turbine capabilities in comparison with the MH interconnection requirements. The next Section 6 will demonstrate these capabilities through transient stability simulations. 5.1 Turbine Overfrequency / Underfrequency Ride-Through Capability A typical generator connected to the MH network should stay connected if the frequency remains within the limits given in Table 4.

5.1.1 Turbine A The wind turbine has the capability to operate between 57 Hz and 62 Hz continuously. The wind turbine has adequate underfrequency ride-through capability. The MH Transmission System Interconnection Requirements document [1] states that the Generation Facility is to remain connected if the frequency is in the range of 62.0-63.5 Hz for 30 seconds. MH has agreed that the overfrequency capability of 62 Hz continuous will be adequate for connecting to the MH transmission grid. 5.1.2 Turbine B The Turbine B frequency ride-through capability is summarized in Table 5.

The wind turbine has adequate underfrequency ride-through capability. The MH Transmission System Interconnection Requirements document [1] states that the Generation Facility is to remain connected if the frequency is in the range of 62.0-63.5 Hz for 30 seconds. MH has agreed that the overfrequency capability of up to 62.5 Hz for 30 seconds will be adequate for connecting to the MH transmission grid.

5.2 Turbine Overvoltage / Undervoltage Ride-Through Capability Table 6 summarizes the overvoltage and undervoltage requirements at the Elie 230 kV bus during local and remote disturbances. The worst undervoltage cases occur during 230 kV faults near the Elie station. The worst system overvoltage cases typically occur when large amounts of power from the HVdc system are lost (e.g. trip of Manitoba-USA 500 kV line followed by an HVdc reduction, or a permanent or temporary block of a bipole).

Undervoltage Overvoltage

Fig. 1. Voltage Requirements for Interconnection to Elie 230 kV bus.

5.2.1 Turbine A The Turbine A wind turbine can operate continuously between 90% and 110% voltage [2]. It has the capability to operate up to 115% voltage for 5 seconds. The wind turbine will trip off within 100 ms if the voltage at the wind turbine 600 V bus exceeds 115% [2].

13

The wind turbine will remain connected as long as the voltage does not drop below 70% for more than 2.5 seconds or 15% for more than 0.7 seconds. Within 5 seconds the voltage should recover to a minimum of 90%. The overvoltage ride-through capability of the wind turbine does not meet Manitoba Hydro’s overvoltage criteria. A voltage control scheme would be required to ensure the voltage on the wind turbine’s 600 V bus does not exceed 1.14 pu allowing a 0.01 pu voltage trip margin. This voltage control scheme will be described in section 7.0 of the report. The undervoltage ride-through capability of the turbine meets Manitoba Hydro’s undervoltage criteria. 5.2.2 Turbine B The Turbine B wind turbine can operate continuously between 90% and 110% voltage. It has the capability to operate up to 115% for 1.0 second, and between 115% and 130% for 100 ms. With the Turbine B Low Voltage Ride Through (LVRT) option II, for line-to-ground or three-phase-to-ground faults, the wind turbine will remain connected as long as the voltage does not drop below 70% for more than 1.0 second or 15% for more than 0.625 seconds. Within 3 seconds the voltage should recover to a minimum of 90%. For line-to-line faults, the wind turbine will remain connected as long as the voltage does not drop below 70% for more than 1.0 second or 15% for more than 0.2 seconds. Within 0.2 seconds the voltage should recover to a minimum of 70%, and within 3 seconds to a minimum of 90%. The overvoltage ride-through capability of the wind turbine does not appear to meet Manitoba Hydro’s overvoltage criteria. However, due to the fast voltage control capability of the doubly-fed induction generator, the Turbine B wind turbine controls actually aid in reducing the worst-case overvoltage at the Elie 230 kV bus and at the Turbine B 575 V generator bus, thus the Turbine B wind turbine is able to ride through the worst-case overvoltage. This voltage control capability will be demonstrated in section 6.0 of the report. For line-to-ground and three-phase-to-ground faults, the undervoltage ride-through capability of the turbine (LVRT option II) meets Manitoba Hydro’s undervoltage criteria. For line-to-line faults, the undervoltage ride-through capability is acceptable when considering normal clearing times, however the turbine will trip out for slow-clearing stuck breaker (NERC Category C) faults. MH has agreed to accept the reduced line-to-line fault ride-through capability for this particular case because the wind farm would only trip due to a low-probability NERC Category C fault. Transient stability simulations indicated no adverse system impacts due to a wind farm trip in this scenario.

5.3 Reactive Power Requirements The Manitoba Hydro Transmission System Interconnection Requirements document [1] states that any Generation Facility greater than 10 MW comprised of induction type generators (such as may be connected to wind turbines) provide reactive supply that is able to control the voltage level by adjusting the machine’s power factor between a minimum of 0.95 overexcited and 0.95 underexcited as measured at the Generator intermediate bus. The power factor requirements could be larger depending on transient stability analysis. 5.3.1 Turbine A The Turbine A wind turbines come equipped with 49 MVAr power factor correction capacitors installed on the 600 V generator bus. At rated output, the wind farm will absorb 42.1 MVAr. Additional VAR support will need to be installed to provide the leading power factor requirement. The Turbine A turbines will need to be installed with 3x10 MVAr switched capacitors, plus an 8 MVAr STATCOM. The details of the additional VAR support and associated voltage control scheme will be discussed in upcoming sections 6 and 7. 5.3.2 Turbine B The Turbine B wind turbines consist of doubly-fed induction generators, which have inherent fast reactive power control capability ranging from 0.95 overexicted to 0.9 underexcited. The Turbine B turbines meet the Manitoba Hydro reactive power requirements.

6.0 Stability Investigation Relevant stability plots are included in Appendix E. The IFS was originally performed assuming Connection Option A. Worst transient stability cases were re-run for Connection Option B and are discussed in the upcoming sections. 6.1.1 Study Stability Models The two base case system models used in the transient stability analysis were based on updated 2004 series MAPP stability models, and included:

A. 2009 summer off-peak system intact with maximum MH-US transfer: MHEX=2175, NDEX=1950

B. 2009 summer peak system intact with maximum generation in Manitoba Dorsey DC was the sink for the 99 MW Elie wind farm. 6.1.2 Disturbances The following NERC category B (single component) and C (multiple components) disturbances were tested to determine the impact of the Elie generator on the Manitoba-US transfer capability, using the 2009 summer off-peak stability model (case A above):

I. ag1 fault – 4-cycle SLF 345 kV fault at Leland Olds on Ft. Thompson line. Stuck breaker. Clear faulted line at 11 cycles.

II. ei2 fault – permanent bipole fault on the CU DC line. Both Coal Creek units tripped at 0.28 seconds.

III. mqs fault – SLG fault at Sherco unit #3 with breaker fail 8N28. Trip Sherco unit #3. IV. nbz fault – 4-cycle 3-phase 500 kV fault on at Chisago on Forbes line 601. Cross-

trip D602F. V. mat fault – Loss of D602F with DC reduction.

The following NERC category B (single component) and C (multiple components) disturbances were tested to determine the impact of the Elie generator on the transfer capability within Manitoba, using the 2009 summer peak stability model (case B above):

I. System intact, 3-phase normal clearing faults on lines D12C Dorsey-Elie, D12C Elie-Cornwallis, D14S, S53G, S60L, Y51L, G37C, D54C, and C28R.

II. System intact, single line-to-ground stuck breaker (slow clearing) faults (determined from ACCC analysis as candidate for stability analysis).

III. Prior outage, 3-phase normal clearing faults (determined from ACCC analysis as candidate for stability analysis).

IV. mbs fault – Loss of Manitoba HVDC bipole loaded at 1882 MW at Dorsey. No cross-trip of Manitoba-Ontario tie lines.

16

6.2 System Underfrequency Ride-Through Test The ‘mbs’ fault (loss of Manitoba HVDC bipole, no cross-trip of Manitoba-Ontario tie lines) is the disturbance used to test the underfrequency ride-through capability of the wind turbines, as well as to observe the impact of the wind farm on system frequency. The transient frequency is to remain above 59.3 Hz, without any reduction in wind output. Please refer to figures in Appendix E-1. 6.2.1 Turbine A The Turbine A wind farm remained connected throughout the disturbance. There were no significant impacts of the wind farm on the system transient frequency, and no reduction in wind output was observed. The Turbine A turbine meets MH underfrequency criteria. 6.2.2 Turbine B The Turbine B wind farm remained connected throughout the disturbance. There were no significant impacts of the wind farm on the system transient frequency, and no reduction in wind output was observed. The Turbine B turbine meets MH underfrequency criteria. 6.3 System Overvoltage Ride-Through Test The ‘nbz’ fault (4-cycle 3-phase 500 kV fault on at Chisago on Forbes line 601. Cross-trip D602F with DC reduction) is the disturbance used to test the overvoltage ride-through capability of the wind turbines. To test for the worst-case scenario, the pre-disturbance intermediate bus voltages were set to as high as was reasonable for the particular cases. Because of the proximity of the Elie wind farm to Dorsey station, overvoltages as high as 1.22 pu are possible at the 230 kV bus. Please refer to figures in Appendix E-2. 6.3.1 Turbine A The Elie wind farm was first set to have 34.5 kV 4x10 MVAr capacitors and all 49 MVAr PFCs in-service as a worst-case scenario. The 230-34.5 kV transformer was modeled with an OLTC controlling the 34.5 kV pre-disturbance bus voltage. Connection Option A: The Turbine A wind farm tripped out during the disturbance as voltage at the generator 600 V bus exceeded 115% if the pre-disturbance 34.5 kV bus voltage was greater than 1.01 pu. The Turbine A turbines do not meet the MH transient overvoltage criteria. Mitigation in the form of an on-load tap changer voltage control scheme on the 34.5-230 kV transformer would be required to keep the Turbine A wind farm on-line during this disturbance. If the pre-disturbance 34.5 kV bus voltage is controlled to a maximum of 1.0 pu, the Turbine A turbines remain connected.

17

Next, the Elie wind farm was set to have 34.5 kV 3x10 MVAr capacitors and all 49 MVAr PFCs in-service as well as an 8 MVAr D-STATCOM on the 34.5 kV bus. The 230-34.5 kV transformer was modeled with an OLTC controlling the 34.5 kV bus voltage. The Turbine A wind farm remained connected throughout the disturbance if the pre-disturbance 34.5 kV bus voltage was controlled to a maximum of 1.02 pu. Mitigation in the form of an on-load tap changer voltage control scheme on the 34.5-230 kV transformer would be required to keep the Turbine A wind farm on-line during this disturbance. If the steady state 34.5 kV bus voltage is controlled to a maximum of 1.02 pu, the Turbine A turbines remain connected if an 8 MVAr STATCOM is installed. Connection Option B: Similar tests were performed for Connection Option B. Due to the weaker radial connection to Dorsey combined with the voltage-square effect of the capacitors, the overvoltage at the wind generator bus was found to be slightly worse. In this case, the Turbine A wind farm remained connected throughout the disturbance if the pre-disturbance 34.5 kV bus voltage was controlled to a maximum of 0.99 pu. Mitigation in the form of an on-load tap changer voltage control scheme on the 34.5-230 kV transformer would be required to keep the Turbine A wind farm on-line during this disturbance. If the steady state 34.5 kV bus voltage is controlled to a maximum of 0.99 pu, the Turbine A turbines remain connected if an 8 MVAr STATCOM is installed.

6.3.2 Turbine B The Turbine B wind farm voltage control scheme was set to control the 230 kV POI voltage to 1.06 pu as a worst-case scenario. The Turbine B wind farm remained connected throughout the disturbance for both Connection Options A and B. The fast voltage controls of the doubly-fed induction generator aided in slightly reducing the overvoltage seen at the Elie 230 kV bus when compared to the case without the wind farm. The Turbine B turbines meet the MH transient overvoltage criteria. 6.4 Undervoltage Ride-Through Test All of the close-in three-phase and single line-to-ground faults can be regarded as undervoltage ride-through tests. It should be noted that the 230-34.5 kV transformer impedance is important is determining the voltage on the generator bus due to a nearby system fault. This transformer was modeled with 8.5% impedance on a 100 MVA base.

18

6.4.1 Turbine A The Turbine A wind farm was observed to ride through all close-in faults. A three-phase fault on the Elie 230 kV bus resulted in a voltage of 0.205 pu for 83 ms at the 600 V generator bus. A stuck breaker single line-to-ground fault resulted in a voltage of 0.65 pu for 267 ms at the 600 V generator bus. Both faults are within the turbine’s capability. The Turbine A turbines meet the MH undervoltage ride-through criteria. 6.4.2 Turbine B The Turbine B wind farm was observed to ride through all close-in three-phase and single line-to-ground faults. A three-phase fault on the Elie 230 kV bus resulted in a voltage of 0.167 pu for 83 ms at the 575 V generator bus. A stuck breaker single line-to-ground fault resulted in a voltage of 0.74 pu for 267 ms at the 575 V generator bus. Both faults are within the turbine’s capability. The Turbine B turbines have a stricter undervoltage criteria of 15% for 200 ms for line-to-line faults, after which the voltage must immediately jump back to 0.7 pu. The wind farm can ride through a normal clearing line-to-line fault (83 ms), but a stuck breaker line-to-line fault (267 ms) will result in the wind farm tripping out. With a two-breaker ring bus at Elie, any stuck breaker scenario will result in loss of the wind farm anyways. Transient stability simulations indicated no significant adverse system impacts due to a wind farm trip in this scenario. The Turbine B turbines meet the MH undervoltage ride-through criteria for this particular wind site. 6.5 System Intact with Local N-1 Contingencies For Connection Option A, the worst-case local line fault scenario for the Elie wind farm is a normal clearing three-phase fault on line D12C between Dorsey and Elie. The fault clearing leaves the wind farm with a much weaker connection to the grid because the line to Dorsey has been lost. For Connection Option B, any fault on the Dorsey-Elie-Portage line will result in loss of the wind farm. Until the remainder of line Dorsey-Elie-Portage is constructed between Elie-Portage, the Elie wind farm is radially connected to Dorsey. Once the line is completed, the next worst-case disturbance would be a fault at Portage with loss of either Dorsey-Portage or Portage-Cornwallis sections of line D12C, however this still leaves Elie connected to the strong Dorsey bus, unlike Connection Option A. Please refer to figures in Appendix E-3.

19

6.5.1.1 Turbine A The Turbine A wind farm tested additional VAR support in the form of 4x10 MVAr capacitors on the 34.5 kV bus. None of the 10 MVAr switched capacitors were in-service for this test. Connection Option A: The Turbine A wind farm caused poorly damped voltage oscillations after fault-clearing if the pre-disturbance 34.5 kV bus voltage was less than 0.97 pu. Mitigation in the form of an on-load tap changer voltage control scheme on the 34.5-230 kV transformer would be required to keep the Turbine A wind farm from violating the minimum 5% damping criteria. If the steady state 34.5 kV bus voltage is controlled to a minimum of 0.98 pu, the Turbine A turbines do not cause undamped voltage oscillations. Connection Option B: The Turbine A wind farm was tested with the pre-disturbance 34.5 kV bus voltage at 0.95 pu. No problems were observed. 6.5.1.2 Turbine B For Connection Options A and B, the Turbine B wind farm remained connected throughout all of the studied disturbances. The fast voltage controls of the doubly-fed induction provided sufficient VAR support such that no local voltage collapse or high local overvoltages were observed. The Turbine B turbine provides acceptable transient stability performance and does not result in local voltage collapse or wind farm overvoltage tripping. 6.6 System Intact with Local N-2 Contingencies Any local Elie 230 kV breaker failure results in a similar situation: loss of line D12C and the 99 MW Elie wind farm. No significant adverse system impacts were observed during this disturbance. A few relay margins were impacted in the range of 1-2%, but remained well within acceptable limits. 6.7 Critical 230 kV Prior Outages with local N-1 Contingencies The generator has expressed a preference to be curtailed during prior outage conditions if necessary rather than installing extra wind farm equipment or paying for line upgrades. Please refer to figures in Appendices E-4 and E-5.

20

6.7.1 Turbine A Combinations of critical 230 kV prior outages and local area three-phase line faults with normal 5-cycle clearing times were tested. The 230 kV prior outages applied to stability cases included lines D12C Dorsey-Elie, D12C Elie-Cornwallis, G37C, and D54C. The worst three-phase faults cases included lines D12C Dorsey-Elie, D12C Elie-Cornwallis, G37C, and D54C. Connection Option A: For the 4x10 MVAr switched capacitor option, if the steady state 34.5 kV bus voltage is controlled to a minimum of 0.98 pu (i.e. 0.99 pu + 0.01 pu) as discussed earlier in Section 6.5.1.1, the Turbine A turbines do not cause undamped voltage oscillations. However this would require a tap-changer control range of 0.99 pu + 0.01 pu, which is too narrow. Instead, the Turbine A wind farm would need 3x10 MVAr switched capacitors plus the 8 MVAr D-STATCOM together with an OLTC with a wider control range of 1.0 pu + 0.02 pu. This will prevent overvoltage tripping and undamped voltage oscillations. With this option, no prior outage curtailment is required for transient stability reasons. Connection Option B: Several prior outage cases were tested. No problems were observed. 6.7.2 Turbine B The same worst-case prior outages and three-phase faults were tested with the Turbine B turbines. The Turbine B wind farm provided an acceptable response in all cases. The Turbine B wind farm does not require any prior outage curtailment for transient stability reasons.

21

7.0 Wind Farm Voltage Control Equipment and Special Protection Schemes The following section summarizes the requirements for each type of wind farm based on the results of the transient stability simulations. 7.1 Turbine A The Turbine A wind turbines would need to install additional capacitive VAR support to meet the 0.95 leading power factor requirement: 3x10 MVAr switched capacitors and an 8 MVAr D-STATCOM must be installed on the 34.5 kV bus. The voltage control scheme for the switched capacitors and STATCOM should be capable of both power factor and voltage control modes of operation. To meet the overvoltage ride-through criteria, to prevent undamped voltage oscillations, and to ensure acceptable steady state operating voltages at the generator buses, the 230-34.5 kV transformer must be equipped with an on-load tap changer. The transformer impedance was modeled to be 8.5%. For Connection Option A, the OLTC is recommended to control the pre-disturbance 34.5 kV bus voltage to 1.0 pu (+/-2.0%). Anything out of this range could result in the wind farm tripping out on overvoltage or producing local undamped voltage oscillations. For Connection Option B, the OLTC is recommended to control the pre-disturbance 34.5 kV bus voltage to 0.97 pu (+/-2.0%). Anything above 0.99 pu could result in the wind farm tripping out on overvoltage for the nbz fault. No undamped voltage oscillations were observed. For Connection Option A only, wind farm curtailment could also be required for 230 kV prior outages of lines G37C or D54C avoid potential thermal overloads on 230 kV line D12C following the loss of line D54C or G37C, respectively. 7.2 Turbine B The Turbine B wind turbines do not require any additional equipment or special protection schemes. They must be equipped with the Turbine B Low Voltage Ride Through (LVRT) option II in order to meet fault ride-through requirements. The Turbine B wind farm will have the capability to control the voltage or VAR flow of the wind farm. For Connection Option A only, wind farm curtailment could also be required for 230 kV prior outages of lines G37C or D54C avoid potential thermal overloads on 230 kV line D12C following the loss of line D54C or G37C, respectively.

8.0 Voltage Quality Analysis 8.1 Introduction There are several types of fluctuations that can affect the voltage quality due to wind power. 1) Tower shadow effect (periodic, f ≈ 1-2 Hz) 2) Wind turbulence (stochastic, average frequency f < 0.1 Hz) 3) Switching of windmills (single events per hour) These phenomena, as well as others such as wind vertical gradients, contribute to voltage fluctuations or flicker. The tower shadow effect is caused by the wind turbine blades periodically passing the wind mill tower three times a cycle for three-blade turbines. This results in a dip in the mechanical torque at each passing, which is transferred to the generator shaft and subsequently seen as a dip in the output voltage. Voltage fluctuations caused by wind turbulence are due to the stochastic as well as the gusty impact of the wind on the turbine. Windmill switching gives rise to voltage dips in the grid each time it happens and can occur several times per hour. Flicker is defined as an impression of unsteadiness of visual sensation induced by light stimulus whose luminance or spectral distribution fluctuates with time. This may be caused by voltage variations. Applying a flicker meter, a ten-minute time-series of measured or simulated voltage variations can be transformed into a short-term flicker value, Pst. A Pst of 1.0 corresponds to the ‘threshold of flicker irritation’ for rectangular voltage changes. The long-term value, Plt corresponds to a period of 2 hours, calculated from a sequence of Pst values: (1) Flicker may be caused both by the continuous and switching operations, such as start-ups, of a wind turbine. The emission of flicker from a wind turbine during continuous operation is adequately described by its flicker coefficient. The flicker coefficient is a normalized measure of the flicker emission from a wind turbine.

Measurements show that the flicker coefficient for a given turbine is a function of the wind speed at hub-height of the wind turbine and the network impedance phase angle of the electric network. It has been shown that the long-term flicker emission (Plt) from a wind turbine during continuous operation is equal to the short-term flicker emission (Pst). The procedure for assessing flicker emission due to switching operations assumes that each wind turbine is characterized by a flicker step factor kf(ψf), being a normalized measure of the flicker emission due to a single worst-case switching operation. The start-up of a wind turbine may cause a sudden reduction of the voltage followed by a voltage recovery after a few seconds. Wind turbines are characterized by a voltage change factor ku(ψf), and this may be used to calculate the expected voltage dip. 8.2 Study Criteria Flicker planning levels are used by Manitoba Hydro for planning purposes and are useful for evaluating the cumulative impact of all fluctuating loads connected to the system. The levels are specified by the utility based on field measurement, historical experience and industry practice. Table 7 lists the flicker limits used for planning new or evaluating existing installations:

Table 7: Flicker Limits.

Industry standards state that the flicker levels shall be at or below the planning levels, 99% of the time, with a minimum assessment period of 1 week.

Also, starting multiple motors may appear to generate periodic fluctuations on the electrical system when each individual motor is started several times within a given time period. To limit the potential of a flicker problem, Manitoba Hydro requires that individual loads or sources do not introduce fluctuations, at their point of interconnection, above the limits given in Table 7. The purpose of these limits is to ensure that cumulative system flicker levels never exceed the threshold of irritation (i.e. Pst=1.0). Dynamic voltage fluctuations are usually caused by motor starting, however, loss of a wind turbine due to excessive wind can cause a brief voltage fluctuation. Dynamic voltage restrictions that are being used by MH are based on IEC Standard 1000-3-7 table 8. The restrictions are repeated in Table 8.

8.3 Procedure for Assessment of Voltage Quality

The following procedure is based on IEC 61400-21, “Measurement and Assessment of Power Quality Characteristics of grid Connected Wind Turbines”.

8.3.1 Voltage Flicker During Continuous Operation The 99th percentile flicker emission from a single wind turbine during continuous operation is estimated by applying equation 2 below: (2) where

is the flicker coefficient of the wind turbine for the given network impedance phase angle, kψ at the PCC, and for the given annual average wind speed, aν at hub-height of the wind turbine at the site;

Sn is the rated apparent power of the wind turbine; Sk is the short-circuit apparent power at the PCC. In the case where more then one wind turbine is connected to the PCC, the flicker emission can be estimated from equation 3 below: (3) where is the flicker coefficient of the individual wind turbine; Sn,i is the rated apparent power of the individual wind turbine; Nwt is the number of wind turbines connected to the PCC.

Equation 3 assumes that the maximum power levels between wind turbines are uncorrelated. Under special conditions, however, wind turbines in a farm may ‘synchronize’, causing power fluctuations to coincide. Equation 3 would then underestimate the flicker emission. 8.3.2 Voltage Flicker During Switching Operations The flicker emission due to switching operations of a single wind turbine shall be estimated by applying equations 4 and 5 below.

(4)

(5) where )( kfk ψ is the flicker step factor of the wind turbine for the

given kψ at the PCC. In the case where more than one wind turbine is connected to the PCC, the flicker emission from the sum of them can be estimated from equation 6 and 7 below. (6) (7) where N10,i and N120,i are the number of switching operations of the individual wind

turbines within a 10 min and 2 h period; kf,i ( kψ ) is the flicker step factor of the individual wind turbine; Sn,i is the rated power of the individual wind turbine.

8.3.3 Voltage Fluctuations The relative voltage change due to a switching operation of a single wind turbine is estimated by applying equation 8 below. (8) where d is the relative voltage change in %; ku )( kψ is the voltage change factor of the wind turbine for the kψ given at

the PCC. In cases where more than one wind turbine is connected to the PCC, it is not likely that even two of them will perform switching operations at the same time. Therefore, no summation effects need to be taken into account to assess the relative voltage change of a wind turbine installation according to the IEC standard. 8.4 Turbine A The St. Leon IES [4] provided voltage flicker for the NEG MICON NM72C/1500 turbines according to IEC 61400-21 for continuous and switching operations. It is assumed that the Turbine A turbines will have very similar IEC 61400-21 data. Based on these calculations, flicker is not expected to be a problem at the Elie wind farm location. 8.5 Turbine B Similar IEC 61400-21 calculations were performed for the Turbine B turbines and flicker is also not expected to be a problem at the Elie wind farm location. All flicker calculations were within the Manitoba Hydro flicker standards.
