Stability enhancement in SVC based controller design using Differential Evolution algorithm

This paper describes the power system stability enhancement in Static Var Compensator (SVC) based damping controller. Here Proportional Integral Derivative (PID) and Lead-Lag (LL) controllers with associated time delay are considered for the proposed study. To find out the optimal controller parameters, Differential evolution algorithm is applied. The performance of the given controller is analysed under different disturbances for single machine infinite bus power system. To effectiveness and robustness of the proposed controllers, the various simulation results are compared under various disturbances and operating conditions.
