Network requirements of future energy conversion technologies

Especially the introduction of intermittent electricity sources and the diffusion of distributed generation will make it necessary to improve the electricity network capacities and control mechanisms and will make the introduction of completely new dispatching philosophies necessary. The paper discusses the expected problems of the UCTE net introduced by the possible installation of25 GW off-shore wind power in the North and Baltic sea. An up-grade of the transport capacities will become necessary to make the power available all over Gennany. Control problems might especially arise, if a rapid shut down of the wind turbines in a stonn situation would occur. The dispatching philosophy has to be changed from a demand driven to a supply driven philosophy, which distinguishes between renewable - primary - supplies and back-up - secondary supplies.
