3 DS3 - Changing DS3 Areas System Performance System Policies System Tools

4 DS3 - Changing DS3 Areas System Performance System Policies System Tools

5 System Performance System Services DSM Performance Monitoring Grid Code ROCOF

6 RoCoF CER decision paper April 2014 UR decision paper May 2014 Generator Studies Project TSO-DSO Implementation Project Alternative Solutions Project

7 Generator Categorisation TSOs’ assessment of prioritisation based on: –Run hours (existing/forecast) –Constrained-on –Priority dispatch Generator Capability studies to begin shortly 7

8 Alternative Solutions Project 8 Range of theoretical options assessed at a high level via weighted scoring matrix approach Subset of viable options (2 to 3) selected for Phase 2 analysis Phase 1 (5 months) More detailed review of the viable options from Phase 1 Analysis focused on technical and financial aspects of each option Phase 2 (13 months) Joint project by TSOs Communication with industry via DS3 Advisory Council and website

9 System Services DS3 System Services Procurement Design –Competitive Multi Bid Auction and Regulated Tariff Decision paper by end of 2014

10 Demand Side Management DSU Grid Code Working Group –4 modification approved by the Ireland GCRP –Further consultation on frequency requirements and performance monitoring –SONI consultation on Grid Code modifications ESBN and NIE expressed concerns about impact of DSUs on their system security Work on identifying and removing barriers to service provision close to completion DSU 150 MW AGU 85 MW Powersave 10 MW STAR 45 MW Economy 7 Night Saver

11 DS3 – Shaping the System of the Future Frequency Voltage Renewable Data

12 Realising Potential of DSO Generation Transmission 110kV Distribution 33kV TSO-DSO Engagement

13 Voltage Control 2025Power Factor of TYPE B Wind CAUTEEN MVAr CAUTEEN WP0.95 Leading145 WP0.98 Leading105 WPUnity Power Factor55 WPVoltage control ± ESBN implemented TSO-DSO agreed changes at Cauteen wind farm cluster Interim measure to improve voltage stability in the area Wider reactive compensation studies underway –Value of DSO windfarms: significant off setting of transmission reactive compensation requirements

14 Operational Studies Voltage Dip Induced Frequency Dip (VDIFD) studies – due mid Nov Ramping policy study and tool – due end 2014 Minimum no. of conventional generation – complete * High SNSP Report – H complete * High wind speed shut down report – complete * Automated approach to large scale dynamic studies using Plexos – pilot complete

15 DS3 – Shaping the System of the Future WSAT Control Centre Tools Model Dev. & Studies

16 CCT and WSAT CCT Wind dispatch tool went live in Belfast on 24/07/2014 –DCC Constraint –Developer Outage –High Frequency/Min Gen –RoCoF/Inertia –SNSP Issue –Test – Developer –Test – TSO –Transmission Constraint WSAT Validation of dynamic model performance underway – (1) tuning and (2) cross validation using real events
