Minimizing power system oscillations and enhancing stability are one the main challenge of designers and operators. So far, various options have been proposed for it. Unified Power Flow Controller (UPFC) is one the most powerful equipment of Flexible AC Transmission Systems (FACTS) which has been used to perform this work. So in this paper, UPFC has been employed to improve dynamic performance of power system. Using PSO algorithm to extract optimal parameters of UPFC is other capability of this paper. Simulation has been performed by MATLAB algorithm and case carried out on a power system
