Abstract: This paper contributions a fuzzy Logic Controller for Automatic Generation Control (AGC) is considered for both area like two-area hydro-thermal and four area non-reheat thermal power plant. In the modern power association, the AGC of both system has generally consumed in frequency control outstanding to taking the profligate comebacks. The model of hydro-thermal system and four area non-reheat thermal system with fuzzy is simulated in MATLAB/SIMULINK platform. The dynamic reactions of load frequency control by fuzzy and its related determined with PID controller for frequency management. The accomplishment of the projected fuzzy is better-quality the expectations of power system in provisions of settling time, peak undershoot time and peak overshoot time for two area hydro-thermal and four area relation of setting time and peak undershoot time is improved . Proposed Fuzzy Controller is better result offers as compared to PID for both area such as hydro-thermal power plant and four area power plant.
