Abstract

This paper demonstrates an application of fuzzy logic to the load-frequency control (LFC) using fuzzy gain scheduling of PI controllers. The controller has been designed for a single area system, two-area interconnected power system. The fuzzy based PI controller is designed using a set of control rules, and the control signal is directly deduced from the knowledge base and the fuzzy inference. A comparison between a conventional PI controller and the proposed fuzzy controller is presented and it has been shown that the proposed Fuzzy controller can generate the best dynamic response with less overshoot and settling time following a step load change.

Keywords

load-frequency control (LFC), Fuzzy controller.
