Application of WOA-RBF-PI Controller in Voltage Control of SVC

The traditional PI voltage controller in SVC can't meet the requirements of rapidity and stability. In order to solve this problem, this paper combines whale optimization algorithm with RBF neural network to design WOA-RBF-PI voltage controller, which realizes the online adjustment of PI control parameters. The simulation results show that when the WOA-RBF-PI voltage controller designed in this paper is applied to SVC, it has better fast response ability and robustness, and can reduce the overshoot to make the system show good dynamic stability performance. Its control effect is better than that of conventional PI control, which can better play the role of SVC in maintaining system voltage stability and providing reactive power support.
