Abstract :A genetic algorithm insert ignore into journalissuearticles values(GA);-based sliding mode controller is proposed to improve the voltage stability of a power system with a static var compensator. The proposed controller is examined for improving the load bus voltage, which changes under different demanding powers, and its performance for transient analysis is compared with the Ziegler--Nichols proportional-integral insert ignore into journalissuearticles values(ZNPI);, Lyapunov-based sliding mode control insert ignore into journalissuearticles values(LASMC);, and GA-based proportional-integral-derivative insert ignore into journalissuearticles values(GAPID); controllers. The dynamic equations, consisting of a 2-bus nonlinear system, are converted to a mathematical description of sliding mode techniques. The optimum values of the sliding mode controller and proportional-integral-derivative insert ignore into journalissuearticles values(PID); coefficients that are required are calculated using the GA technique. Output voltage performances are obtained based on the demanding powers, which are at a constant variation. In this process, sliding mode, ZNPI, GAPID, and LASMC controllers are preferred in order to control the system. The results show that the GA sliding mode controller method is more effective than the ZNPI, GAPID, and LASMC controllers in voltage stability enhancement.
