The paper presents a hybrid standalone power conversion strategy for the integrated connection of multiple remote loads. The proposed system consists of fuel cells, PV panels, a wind turbine and batteries. The primary aim of the proposed controller is to operate the fuel cells about their maximum efficiency region. A proposed control technique for charging and discharging allows the renewable energy sources to maintain the battery charge (where possible) as well as supply to the load, or maintain the battery charge and other sources to directly supply the load, or to charge the battery when it is possible.
