| Abstract | ||
| This paper is studying the improvement of the power system stability by optimal design of variable structure controller (VSC) and power system stabilizer (PSS) based on Particle Swarm Optimization (PSO) . Switching vector and the switching feedback gains optimal values of variable structure controller and optimal parameters of power system stabilizer are finding by using Particle Swarm Optimization (PSO). The variable structure controller and power system stabilizer parameters are tuned optimally to minimize the objective function of the problem . By Using each of optimal (VSC) and optimal (PSS) with the developed model of a single machine infinite bus power system and after comparison the simulation results of two controllers, The results of using the optimal VSC design shows it provides a simple method for arriving to the settings of the VSC and optimal VSC improved the power system stability best than PSS | ||
