Abstract—In this paper a novel approach for power management and control strategy of a wind/fuel cell/battery-bank hybrid power generation/storage system are proposed. The system consists of a wind turbine and a proton exchange membrane fuel cell (PEMFC) as power generation systems, battery bank and electrolyzer, as long term and short term storage systems respectively and also different converters with different control strategy. The produced power of wind system is unpredictable. Due to this reason, a wind power system may be combined with other power sources. In this paper, wind power system is integrated with fuel cell due to its high efficiency, modularity and fuel flexibility. The battery bank is used to alleviate slow dynamics of fuel cell by providing excess power during transient event such as step load demand and also during above the maximum power available from fuel cell (FC) and wind turbine (WT) systems for short duration. Moreover, the proposed hybrid power generation can tolerate rapid changes in wind speed. In wind turbine, a comprehensive torque model for three-bladed wind turbine including effects of wind shear and tower shadow is considered. Simulation results with MATLAB software have been presented to point out the validity of proposed system.
