Expected Generation & Demand (between 2009 and 2018)
In the Generation Capacity Projection study covering between years 2009 and 2018,
Peak Demand 55,053 MW (high scenario) 51,757 MW (low scenario)
Installed Capacity 56,382 MW (high scenario) 54,240 MW (low scenario)
The projection study results show that the possible back up ratio of the installed capacity is %45.4 for 2009 and %2.4 for 2018. After 2015 new generation additions are needed.

Recent Situation for Wind Generation in Turkey
• 4916 MW evaluated by TEIAS in respect of connection to PS
• 3321 MW of these applications has been licensed by EMRA
• 658 MW is in Operation • 2000 MW is Underconstruction
• 78.000 MW new application are under evaluation
• The amount of the available wind generation capacity can be connected to the system until 2013 is 12000

Wind Enery Potential Atlas is ready (http://repa.eie.gov.tr)
The law (no:5346) for the “Utilization of Renewable Energy Sources for the Purpose of Generating Electricity” issued in 2005.
The Grid Code for the Wind Power Plants has been prepared by TEIAS
and approved by EMRA.

Fault Ride Through Capability of the Wind Power Plants
Diagram-1
Investment Workshop 11-12 November 2009 13
In the event of the fault if the voltage stays in the region numbered 1, active power of the wind turbine should be increased with the rate of %20 of its nominal power in one second and it should reach its max. active power value which can be generated as soon as the fault cleared away.
In the event of the fault if the voltage stays in the region numbered 2, active power of the wind turbine should be increased with the rate of %5 of its nominal power in one second and it should reach its max. active power value which can be generated as soon as the fault cleared away.

The Reactive Power Support of the Wind Power Plants The wind turbines will not give any reaction up to 10% of the grid
voltage oscillations.
For the voltage oscillations more than this limit, for each 1% changes in nominal voltage, the reactive current support is required which is equal to 2% of the nominal current (Diagram-2).
The reactive support should be realized in 20 millisecond and it should continue for 3 seconds as shown in Diagram-1.
Investment Workshop 11-12 November 2009 16
Active Power Control
In necessity, the active power output of the wind power plants should be automatically controlable with the rate of %20-%100 of it’s total installed capacity with the signals will be sent by TEİAŞ.
a) The speed of the load shedding in minute for the Wind Power Plants which have installed capacity equal or less than 100 MW will be %5 of it’s installed capacity.
b) The speed of the load shedding in minute for the Wind Power Plants which have installed capacity higher than 100 MW will be %4 of it’s installed capacity.

Frequency Reaction of WPP’s
If the frequency of the grid is higher than 50.2 Hz, there will be no permission for additional WPP’s connection to the grid.
Wind turbines will be able to generate all of it’s available capacity on the condition that the grid frequency is between 47.5-50.3 Hz.
In the condition that the grid frequency is higher than 50.3 Hz, the curve in diagram-3 will be followed and for each 100 mHz frequency increase, load sheding will be applied with the rate of %5 of it’s available capacity.

Technical data which is required from Wind Power Plants by TEİAŞ
Number of wind turbines and nominal power (MWe) and the type of each turbine (asynchronized , synchronized ).
Grid Connection types of turbines (directed; double fed, synchronized generator, AC/DC/AC converter synchronized generator).
Operational conditions of wind turbines for minimum and maximum wind speed values (the graphics which shows the changes in the generation of wind power plants according to the wind speed).
The type and the label of systems will be constructed to limit the flicker effect of voltage and current harmonics.
