Due to the popularity of renewable sources of energy generation of power for the alternative electrical energy source is not practical in a traditional way. During the past years remarkably photovoltaic and wind generation of power is highly expanding. In this work, the combination of wind turbine generator and the solar panel is the proposed hybrid energy system which is the further source for a power system with conventional sources like hydro and thermal power generation. To track the point of operation a basic control method is proposed in which wind turbine generator coerces excessive power and also excessive power from PV is coerced under stable environmental changes. The proposed DC-DC converter provides a constant voltage to the voltage source inverter from the hybrid energy system. The Maximum power point tracking methods perturb and observe algorithm utilized to extract extreme power from the hybrid system. With simulation results which evaluate the system feasibility, the whole hybrid system is illustrated. A Matlab/Simulink model is evolved using software simulation.
