An outline of an active power reserve sharing process across continental Europe

Abstract

The implementation of reserve sharing allows system operators to jointly use their active power reserves. In synchronous areas that feature a decentralized load-frequency control structure, a reserve sharing process couples local frequency restoration resources, which is a prerequisite for integrated ancillary service markets. It also offers the possibility of decreasing the overall amount of frequency restoration reserves in the synchronous area. This paper gives a summary of a large-scale implementation across Continental European areas with limited cross-border transfer capacity by means of multi-objective optimization. A model of the European power system with 22 control areas is used to apply the algorithm. The framework is tested for its practical applicability and policy implications are discussed.
