A Comparative Performance Analysis of Automatic Generation Control of Multi-Area Power System Using PID, Fuzzy and ANFIS Controllers

Automatic generation control (AGC) of four-area interlinked power system with generation rate constraints (GRC) is presented in this paper. The four-area interconnected power system having two areas with steam turbines and other areas are nuclear and hydro turbine tied together with power lines is considered in this paper. The AGC of multi-area power system using PID, Fuzzy and ANFIS controllers, and their comparative performance analysis are presented in this paper. ANFIS is a hybrid intelligent controller formed by parallel combination of fuzzy logic and neural network. This controller is able to control the frequency deviation efficiently and at minimum time, so ANFIS controller gives improved result over fuzzy and PID controllers.
