dc.description.abstractThis paper proposes an evolutionary fuzzy lead-lagcontrol approach for coordinated control of flexible AC transmissionsystem (FACTS) devices in a multi-machine power system.The FACTS devices used are a thyristor-controlled series capacitor(TCSC) and a static var compensator (SVC), both of whichare equipped with a fuzzy lead-lag controller to improve powersystem dynamic stability. The fuzzy lead-lag controller uses afuzzy controller (FC) to adaptively determine the parametersof two lead-lag controllers at each control step according to thedeviations of generator rotor speeds. This paper proposes an AdvancedContinuous Ant Colony Optimization (ACACO) algorithmto optimize all of the free parameters in the FC, which avoids thetime-consuming task of parameter selection by human experts.The effectiveness and efficiency of the proposed evolutionaryfuzzy lead-lag controller for oscillation damping control is verifiedthrough control of a multi-machine power system and comparisonswith other lead-lag controllers and various population-basedoptimization algorithms.en_US
