Abstract
In this paper improvement in voltage sag by using PSO optimized fuzzy controller is described. Dstatcom is the FACTS device used in voltage sag improvement. Particle swarm optimization (PSO) is used to optimize the if then rules of the fuzzy controller. In this system a Dstatcom is placed in a three phase system to control the voltage sag. A fuzzy controller is designed to control the output of Dstatcom. The whole system is simulated using MATLAB Simulink. The fuzzy controlled Dstatcom output is compared with a PI controlled Dstatcom output. The system without Dstatcom is also simulated using MATLAB Simulink. The fuzzy controller rules are optimized using particle swarm optimization and the results are also compared with other systems.
