Abstract

An application of fuzzy logic based control for power systems governingmultiple Flexible Alternative Current Transmission System (FACTS) devices isproposed. Several relations have been derived to determine set points of FACTSdevices using fuzzy reasoning in order to meet the requirements for power flows.These expressions are based on so called coeffcients of influence, which are on-line adapted employing a fuzzy gain scheduling method. The Swiss transmissionnetwork is used to demonstrate and to evaluate the effectiveness of the developedcontrol algorithm.
