Abstract

In this paper multi-objective tuning of a supplementary stabilizer for Static Synchronous Compensator (STATCOM) is presented. A meta-heuristic optimization method named genetic algorithms (GA) is used for tuning the parameters of the proposed stabilizer. The potential of the GA for optimal setting of the proposed stabilizer are investigated. The stabilizer is designed to shift slightly damped and undammed electromechanical modes of power system. The validity of the proposed method is verified on a single-machine infinite-bus power system (SMIB) installed with a STATCOM. Several linear time-domain simulation tests visibly show the validity of proposed method in damping of power system oscillations.
