1 European Wind Integration Study (EWIS) Towards a Successful Integration of Wind Power into European Electricity Grids EWIS Concluding Discussion 13th April 2010, Brussels Network Strengthening findings Mr. Peter Van Roy

2 Content Regional Approach Relationship of Technical Issues Risk Analysis 2015 Network strengthening Priority Areas for immediate Action System Security Analysis Wind Network Compatibility

3 Power System Analysis Regional Approach UK & Ireland Northern Finding situations which indicate regional or global impacts bottom up process CENTRAL WEST SOUTH WEST BALTIC CENTRAL EAST SOUTH SOUTH EAST CENTRAL SOUTH Input for market/grid model: Cooperation to existing studies UCTE IPS/UPS study Dynamic data TradeWind study (EWEA) Wind scenarios Regional models 2013 Questionnaire for 2015 (data provided by indiv. TSOs) Model upgrade for 2015

4 Relationship of Technical Issues Grid Optimization Grid Development Enhance existing grid capability and flexibility by system operator Different measures in different regions to enhance flexibility and capability of the existing grid infrastructure (e.g. available dynamic rating and flow control with phase shift transformers, monitoring and control of wind farms, corrective switching, load flow based scheduling) Maintain System Security Economic grid infrastructure development considering cost effective solutions, use of robust measures to optimize grid usage and an acceptable level of security of supply EWIS beyond 2015 results as a starting point for detailed investigations of sustainable offshore grid infrastructure Legal & market aspects Grid code requirements for generation units to support system security market actions

5 2015 Risk Analysis 1) Existing planned network developments generally sufficient for high wind scenarios in south of Europe; but 2) Additional risk mitigation measures and reinforcements needed to accommodate high wind conditions in Northern Europe. - Onshore installations - Offshore wind park cluster until Bulk power flow - Bottleneck Bulk DC power flow at rated line capacity

8 Priority areas for immediate action 1. ENTSO-E TYNDP EWIS findings and recommendations for the future European wide coordinated planning of the electricity grid within ENTSO-E 2. Progress urgently needed grid infrastructure projects in existing national grid development plans Permitting procedures for grid investments have to be accelerated 3. Start to analyze for the longer term (2020/2025) potential of Offshore grids interconnecting wind farms and countries across the sea and including the implications on Onshore grids.

9 Stability & security assessments Security achieved with expected fault ride through performance Stability measures (stabilisers, etc) adequate but increasingly important as enhanced line ratings exploited North South Mode (0,4 0.5 Hz)

10 Wind Network Compatibility The following objectives summarize the need for grid codes Definition of technical standards for grid connectivity for the prevention of large outages of wind power generation and voltage collapse caused by wind turbines. Adequate FRT requirements, which could also include support to the voltage restoration, and reconnection conditions when tripping Provision of voltage and frequency control Establishment of mechanisms for monitoring and control in real time of wind power by the TSO and fulfillment of grid code compliance Repowering capabilities and treatment of the non-compliant wind generation in case of system faults and security management measures in emergency cases.
