Conclusions Large 300 – 800 MW European wind energy projects are currently developed - mostly Offshore
Wind generator ratings are increasing to 5 MW now and 10 MW in the future for offshore applications
Long (50 – 100 km) HVAC cable interconnections are preferred over HVDC due to cost.
Network Interface Issues, including Energization, System Resonances, Power Quality, Reactive Power and Voltage fluctuations are real concern.
Onshore STATCOM and Filter solutions are possible mitigation solution for grid integration.
Future wind farm concepts may include integrated STATCOM and Energy Storage options.
