Automatic Generation Control of Two Area Power System Using Fuzzy proportional- Integral – Derivative Controller

Abstract

Modern power system networks consist of a number of utilities interconnected networks together . Power is exchanged between utilities over tie-line by which they are connected. Automatic generation control (AGC) plays a very important role in power system. Its main role is to maintain the system frequency and tie-line flow at their scheduled values during normal period and also when the system is subjected to small step load perturbations. In this study, a power system with two areas connected through tie-line is considered. The objective of AGC, based on fuzzy PID controller, is to damp transient deviations(frequency and power)and to provide zero steady-state error of these variables in a very short time. The simulation is implemented by using MATLAB/SIMULINK program. To further adding various types of membership functions and applying for more than two area power system.
