Abstract

Power system stabilizers (PSS) are usually used in power system plants to damp out power system oscillations. In this paper, a simultaneous coordinated tuning procedure of multiple power system stabilizers (PSSs) in multimachine power systems based multiobjective functions Hybridation technique using genetic algorithms (GAs) and the requit simulé (RS). To validate the effectiveness of this tuning approach in enhancing the stability of power systems, modal analysis and nonlinear simulations have been carried out on a multimachine power system.
