Micro Generation



Lessons Learnt

• Make sure and bring the users with you during change

• Leverage your investment in your ‘enterprise solutions’

• More detail in some requirements could of reduced misunderstandings

• Project Resources & Staff Development

• Product Alignment/Product Scoping benefits

• Should have done FAT

• Testing task longer than expected

• Dependencies of GIS changes required

• Staff Communication & Training

• Go-Live Deadline



Our Network Management System

General:

• Is a Priority 1 and business critical IT system

• Core to the Network Operations dept.

Control:

• >148k Switching instructions issued via NMS in 2019

• All Planned and Fault HV switching action logged - Real time Network status

• Safety Management – Records all safety docs and Apparatus Operational Restrictions (AORs)

• Safety built into NMS control tool (Avg of 0.8 Switching incident a year)

Dispatch:

• All faults managed through the system

• Feeds other operations systems such as Fault Intranet

• Uses business rules to predict outage failures

Pain Points

Infrastructure/Setup

• Minimizing downtime

• Partitioning of the critical services from others

• More guidance on purging NMS tables

• Bandwidth required for remote clients

Interfaces

• More API adaptors for key processes (dispatching, Todo’s, reporting)

Application

• Web Callbacks limitations

• TopVal limitations (filtering & acknowledging correct)

• Inability to display Clues in Lookahead (e.g. Hazards)

• Managing documents,

• Patching problems (Deleting maps, Master devices)

• Impacted customers requires a study mode session



Future Plans

Continue working with Oracle on DSO functionality and enhancement requests

NIE Networks CVP

DERMS Enhancements

1. Ability to present Powerflow figures per generation type and demand for real and reactive power at Transmission and Distribution Boundary Points.

2. Ability for a pre-logged switching job to run Powerflow and identify any potential violations or warnings depending on expected weather for enhanced Outage Management planning

3. Ability to manage and provide services to the system operator (FFR, SFR, SSRP)

4. Ability to forecast all the above 4 days in advance.

5. Ability to have Active Network Management (ANM) control via NMS.

6. Ability to allocated capacity to customers to ensure no violations on the network.



Fast Frequency Response (FFR)

Tripping Tx for demand reduction
