Abstract

Static var compensator（SVC）is a typical economical and reliable first-generation of FACTS device and is used widely in maintaining the voltage stability of the power system and therefore is of great significance. In view of the problem of traditional PI control in SVC voltage control

its control structure is improved by introducing nonlinear functions and

at the same time

its PI control parameters are optimized with combination of intelligent algorithms and also by the use of the improved genetic algorithm. The simulation experiment results show that the performance of SVC after corresponding optimization has a definite improvement in the field of voltage control

has better control effect as well as a certain reference for related research work.
