TWO AREA CONTROL OF AGC USING PI & PID CONTROL BY FUZZY LOGIC

This work presents an efficient method based on a modified fuzzy PI control with parallel fuzzy PD control for automatic generation control (AGC) of a two-area power system. This describes the control schemes required to operate the two-area power system in the steady state. The model of a two-area power system is established using the equations describing dynamic behaviour of a two-area power system and control schemes in Matlab-Simulink program respectively. The performances of different controllers for variable inputs are compared for the same two area power system. The dynamic response of the load frequency control problem are studied using MATLAB simulink software. The results indicate that the proposed Fuzzy logic controller exhibits better performance.
