WHY RTE INITIATED THE WHY RTE INITIATED THE «« IPESIPES »» PROJECT?PROJECT?
Potential security troubles beyond a threshold of 3 GW of wind power connected to the network (3.5 GW reached in April 2009 with 98% MV connected).
Controlling the risks requires, at first, a real-time monitoring of wind generation and the ability to make forecasts, in order:
To ensure the production-consumption balance
To manage margins
To check and to forecast transits on the transmission network
