TLDR
Simulation results of the proposed fuzzy controller are presented and it has been shown that proposed controller can generate the best dynamic response following a step load change.Abstract:
In this paper, a fuzzy logic controller is proposed for load frequency control problem of electrical power system. The fuzzy controller is constructed as a set of control rules, and the control signal is directly deduced from the knowledge base and the fuzzy inference. The study has been designed for a three area interconnected power system with generation rate constraint. Simulation results of the proposed fuzzy controller are presented and it has been shown that proposed controller can generate the best dynamic response following a step load change. Robustness of proposed controller is achieved by analyzing the system response with varying system parameters.read more
