Analysis of controllers for automatic generation control of two area interconnected power system

Abstract

This work presents a brief review and performance comparison of various controllers utilized in past few years for the automatic generation control of the two area interconnected power system. So many controllers like conventional controllers (I, PI, PD, and PID), soft controllers,and fuzzy logic based controllers; fuzzy tuned PID controllers etc. have been utilized for controlling the flow of power in the tie line. In this work fuzzy tuned PID controller is analyzed as the control structure in two area interconnected power system and study is extended for the transient response of the proposed system. In this paper all the prominent controllers and their characteristics have been studied and found that the fuzzy tuned PID controller with PSO technique provides better stability and dynamic response for the system compared to the other existing controllers.
