Abstract
This paper presents the application of STATCOM to enhance damping of Low Frequency Oscillations at a single-machine infinite-bus power system installed with a STATCOM as cast study. Since STATCOM has been considered to damping of Low Frequency Oscillations, therefore the supplementary damping controller based STATCOM like power system stabilizer is designed to reach defined purpose. Artificial intelligence methods like Fuzzy Logic schemes and Genetic Algorithms optimization are considered to design STATCOM supplementary damping controller. To show effectiveness and also comparing these two methods in damping of power system oscillations based STATCOM, the proposed methods are applied and simulated. Several linear time-domain simulation tests visibly show the validity of proposed methods in damping of power system oscillations. Also Simulation results emphasis on the better performance of Fuzzy method in compare with GA method. Simulations are carried out in MATLAB.
