Modeling and Simulation of a stand-alone PV and Fuel Cell Hybrid system for DC Load

Abstract

The increasing demand of electricity and the continuous decrease in the natural reserves of non-renewable energy resources have increased the demand of generation of electricity in the market through renewable energy resources. For DC microgrids, Photovoltaic (PV) and Fuel Cell (FC) generation system is suitable because they supplies DC output. In this paper, PV and FC hybrid generation system is proposed for DC microgrid. The hybrid generation system is operated in an islanded mode. The proposed system is applicable for high voltage appliances and low voltage residential loads. Power electronic boost and buck converter is used for the regulation of voltage at different buses. Performance of the system is analyzed using simulation software MATLAB 2017(a). Results shows the regulated output parameters for the DC loads.
