Load Frequency Control of Hybrid power System using Classical PID Controller

Abstract

This paper addresses the use of PID tuned by Particle Swarm Optimization for frequency control in the hybrid power system. The proposed system composed of renewable sources like wind turbine generation and photovoltaic system with diesel engine generator and storage systems such as the battery, aqua electrolyzer, and Fuel Cell. The stochastic nature of renewable sources causes dangerous fluctuations of frequency and power of the hybrid power system which can provoke the deterioration of electrical equipment. This issue requires an adequate control strategy. Classical PID controller is investigated to give better performance in terms of deviation reduction and elimination of the mismatch between generation and load. The results are shown and compared.
