Coordination and Robust Tuning PSS for Power Systems Using Multiobjective New Hybridation Technic

Abstract:

Power system stabilizers (PSS) are usually used in power system plants to damp out power system oscillations. In this paper, coordinated and robust tuning procedures by Hybridization technique are used. This hybridization is based on multiobjective functions using stochastic (GA) methods and deterministic methods (gradient) and even between themselves stochastic methods (GA-SA). 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.
