摘要: Abstract A completely energy-independent microgrid (green microgrid) was examined in this work with the aims of abating greenhouse gas emissions by spreading use green energy, providing energy backup systems for disaster, and increasing utilization efficiency exhaust heat. This paper analyzed supply to six houses a cold region. The consisted photovoltaics, water electrolyzers, proton-exchange membrane fuel cells (PEFCs), heat pumps. To investigate operation method capacity each piece equipment arrangement, distributed system two or more sets central one set were genetic algorithm. By introducing prior need pattern region into proposed system, based on power balance clarified. partial load performance electrolyzer PEFC analysis program, investigated. It found that area solar cell could be reduced 12% as compared system.
