Genetic algorithm based design of power system stabilizers

Abstract

This paper presents a GA based optimization scheme for simultaneous coordination of multiple machines power system damping controllers. The proposed algorithm is applied to tuning of single and multiple power system stabilizers. Controller design is tested on the small and mid-sized power systems to prove its effectiveness. PSSs are designed using MATLAB control system toolbox and optimized using GAOT toolbox. All models and simulations are carried out using MATLAB and SSAT developed by Powertech Labs Inc, Canada.
