In this paper, we tried to highlight the effect of a power system stabilizer by mentioning a sample and it to be determined the importance of the equipment in the power system that way by modeling and simulating with software MATLAB, was investigated stabilizer effect of the power system on a synchronous machine for complete repelling and dropping of fluctuation and then Particle Swarm Optimization algorithm (PSO) was used to optimize the values of PSS. By using the PSS this fluctuation reduced dramatically, in the final using optimal PSS values we will get a better response.
