Distributed generation of electricity currently has a very important development. Several renewable and free energy sources like the wind (windmills), solar (photovoltaic or thermal) are increasingly used to produce electricity locally on remote sites. Because of the fickleness of the wind and light, energy management is one of the major challenges in wind power systems from the grid, as well as PV-diesel systems. We present in this paper, the design and implementation of an electronic load control module and optimal management of production for hybrid energy systems while ensuring the efficient.
