This system consists of a wind turbine (WT), a proton exchange membrane fuel cell (PEMFC), battery bank, electrolyzer and different converters. In order to solve the problem of intermittent power generation, a wind power system is combined with fuel cell (FC) due to its high efficiency, modularity and fuel flexibility. To alleviate slow dynamics of FC, a battery-bank is used to provide excess power to satisfy load demand above the maximum power available from FC and WT systems for long or short duration. This system is managed by a coordination control strategy base on the dynamic behavior of FC to prevent fuel starvation. Furthermore, it tolerates rapid changes in wind speed or load demand. In wind turbine, a comprehensive torque model for three-bladed WT including effects of wind shear and tower shadow is presented. Simulation results with MATLAB have been presented to verify the mathematical analysis and dynamic modeling of the proposed system.

INTRODUCTION Distributed generation technologies such as fuel cell, photovoltaic, wind turbines, gas turbines, combustion turbines, diesel engines and micro turbines are expected to play an important role in electric power system of the near future. The ever-increasing energy consumption and pollution crises are fast becoming the biggest problems around the world. Consequently, renewable energy sources are attracting more attention as alternative energy sources [1,2]. The integration of renewable energy sources to form a hybrid system is excellent for distributed energy generation. Hybrid power systems combine two or more energy conversion devices to overcome inherent systems limitations. Among the renewable energy, WT and FC generation systems are the most promising renewable power generation technologies [3,4]. However, these renewable energy sources have some weak points when used as stand-alone energy sources. One of the major issues confronting users and designers of wind energy systems is highly dependent on weather conditions [5,6], which makes them unpredictable. To overcome this problem, WT system can be integrated with other alternative systems using hybrid topologies, such as battery bank and FC- electrolyzer system [7–9].
