Optimal PI Controller Design and Simulation of a Static Var Compensator Using MATLAB’s SIMULINK

This paper presents graphic-based simulation and optimal PI controller design of a static var compensator (SVC) using MATLAB’s SIMULINK. Utilization of MATLAB software simplifies problem solving complexity and also reduces working time. In this paper, an optimal PI controller design using genetic algorithms for the SVC was demonstrated. From which satisfactory controller design results, tests against power and three-phase fault disturbances were carried out. Also, comparisons between those results obtained by i) SVC with the PI controller and by ii) using power system stabilizer were examined to evaluate its effectiveness.
