Abstract

In stand-alone microgrids, by employing hydrogen storage coupled with fuel cell, multiple outputs such as electricity, heat, water, and fuel, can be achieved. This study presents an approach to optimize the size of different components of a solar photovoltaic field based microgrid configured with electrolyzer, fuel cell, hydrogen storage and battery bank. The optimum configuration is based on maximizing the utilization of electricity produced by the solar photovoltaic field. Two performance parameters, namely, Unmet Electric Load (fUL) and Excess Electricity (fEX) are defined. The monthly and annual performance of the microgrid is studied for diverse climatic conditions with five climatic zones across six Indian locations as example. As is obvious, the polygeneration microgrid gives the best performance at mountainous zone due to abundant solar radiation. The thermal effects due to sorption and desorption reactions of metal hydride hydrogen storage and fuel cell exhaust provide more than 50 of thermal load in each zone. Even though the optimized configuration can serve the electrical load demand of the different zones, the benefits of polygeneration are more pronounced for mountainous, humid subtropical and arid climatic zones, in that order.
