Hybrid wind/PV/fuel cell generation system

In this paper an energy system composed of three energy conversion devices, namely photovoltaic panels, a wind turbine, and a fuel cell is proposed. A fuzzy logic controller has been designed to provide power to a home on a continuous basis and a hydrogen fuelling station. This controller directs power to a fixed voltage DC bus. The fixed voltage bus supplies the house load, while the excess power is directed to the batteries first and an electrolyzer second, which is used to generate hydrogen for supplying vehicles and a stationary fuel cell. Simulation results proved the effectiveness of the fuzzy logic controller.
