Abstract: This article offerings a Fuzzy Logic Controller for Load Frequency Control (LFC) is deliberated for two-area hydro-thermal power plant. In the recent power organization, the LFC of hydro-thermal system has generally consumed in frequency control outstanding to taking the profligate comebacks. The model of hydro-thermal system with fuzzy is imitation in MATLAB/SIMULINK stage. The dynamic answers of LFC by fuzzy and its associated concluded with PID for frequency control. The achievement of the projected fuzzy is improved-superiority the assumptions of power system in rations of settling time, peak undershoot time and peak overshoot time. Proposed Fuzzy Controller is better result provides as compared to PID for the hydro-thermal power plant.
