3 VENTEEA location and figures VENTEEA is a project focused on the integration of large wind generation within MV distribution networks. In France, more than 95% of the renewable energy generation is connected to the distribution network The project takes place in the Champagne region, France s area with the highest amount of wind generation VENTEEA is supported by the French Agency for the Environment and Energy Management (ADEME) Validé DIR Key facts and figures: 1 existing wind farm 12 MW (dedicated MV feeder) 1 existing wind farm 6 MW (non dedicated MV feeder with 1500 customers) 1 HV/MV transformer (63/20 kv - 20 MVA) 130 secondary substations customers (6 MV feeders) 10 partners (23.5 M - 3,5 years until June 20&16 3

9 DSE - Required accuracy and communications Sensors accuracy: In the French network, voltage limits are 20kV +/- 5% L éolien 8,1 GW Voltage sensors accuracy must be 1% (sensors + acquisition chain + communications to control centres): 0,5 % for the sensor alone would be suitable Active and reactive power sensors accuracy : 3 % Communications requirements: Voltage measurements are synchronised 10 mn averages, calculated and stored in RTU Permanent connecting link between sensors and control centres (GPRS, radio, ADSL) via RTU in MV/LV substations 9
