Abstract: Load frequency control of the hybrid system consisting photovoltaic system and thermal generator is performed in this paper. In this paper Maximum Power Point Tracking is performed in photovoltaic using modified hill climbing algorithm. Modified hill climbing is performed by combining fuzzy logic with hill climbing algorithm. The converter used is Boost converter. DC output obtained is converted to AC output by using single phase inverter. Grid connection is performed by using sinusoidal pulse width modulation. Transfer function model of the whole system is created. Transfer function model of the thermal generator is interfaced with the photovoltaic system to create two area systems. Load frequency controls of this two area system are performed. The simulation of the entire system is performed in the MATLAB SIMULINK.
