Hybrid system name implies the combination of two or more sustainable / non sustainable energy sources. Presently hybrid systems including wind power as one of the basic along with photovoltaic power are more appealing. The primary reason of such hybrid power system is to taken irregularity and unpredictability of wind energy and to make the power supply more reliable. Hybrid wind power with Photovoltaic module can bypass the limitation of wind power irregularity, since Photovoltaic module can acts as an energy barrier and adjust the output power effectively. Wind power and solar energy can mix to form hybrid power system specifically for the power supply. In addition advantage of this kind of hybrid system is that they are the couple renewable energies, which is suitable to the ecological conditions. Two contingences are studied and identified according to power generation from each energy sources, and load requirement. Hill Climb Search algorithm is used as Maximum Power Point Tracking (MPPT) control technique for the wind power system in order to enhance the power generated. The proportional integral control scheme of inverter is intended to keep the load voltage and frequency of the AC supply at stable level indifferent of advance in natural conditions and load. A Simulink model of Hybrid system with DC/DC converter and voltage standardized inverter and energy storage system for stand-alone application developed MATLAB/SIMLINK environment.
