Abstract

A very important matter of discussion in power system operation is the oscillations damping problem. In this paper the authors propose a fuzzy frequency controller (FFC) to improve the dynamic performance of a single-area power system. This paper represents the implementation of fuzzy frequency controller for an AGC in single-area power system. The aim of the proposed controller is to restore the frequency to its nominal value in the smallest possible time whenever there is any change in the load demand etc. The controller provides a satisfactory balance between frequency overshoot and transient oscillations with zero steady-state error. It is found that the proposed controller exhibits satisfactorily well dynamic performance and overcome all possible drawbacks associated with conventional PI controller
