This paper presents the application of Unified Power Flow Controller (UPFC) to enhance damping of Low Frequency Oscillations (LFO) at a Single-Machine Infinite-Bus (SMIB) power system installed with UPFC. Since UPFC is considered to mitigate LFO, a supplementary UPFC like power system stabilizer is designed to reach the defined purpose. Simulated Annealing (SA) is used to tune UPFC supplementary stabilizer. To show effectiveness, the proposed method is compared with another optimization method named Genetic Algorithms (GA). Several linear timedomain simulation tests visibly show the validity of proposed method in damping of power system oscillations. Also simulation results emphasis on the better performance of SA in comparison with GA.
