This paper proposes control strategies for a grid connected Hybrid System (WPVHS) composed of wind turbine photovoltaic array and storage system. The aim is to ensure the service continuity despite the fluctuating behavior of the renewable sources by using a batteries storage system. The proposed control scheme is based on the power balancing in the common DC-link. Hence, the Hybrid System is able to inject desired active and reactive power to the electrical grid. MATLAB software simulation results are provided in order to demonstrate the performance and to show the feasibility of the proposed control.
