Fuzzy logic-based controller for three area power system

Abstract

The paper presents a fuzzy application to the area of Load Frequency Control (LFC) using fuzzy logic-based integral controller. The study is designed for a three area interconnected power system with generation rate constraint. Simulation results of the proposed fuzzy controller are presented. It is shown that the proposed controller can generate good dynamic response, following a step load change. The robustness of the proposed controller is achieved by analyzing the system response with varying system parameters.
