It investigated just to introduction in the cold region houses of a fuel cell cogeneration with geo-thermal heat pump.
1. The optimal operation plan of the compound energy system which composes natural-energy-sources equipment, unused energy equipment, etc., the optimal capacity, and energy loss were clarified. In this study, the method of making a model by the chromosome model which newly used the genetic algorithm although the operation pattern of an energy system is analyzed was proposed. Furthermore, the operation plan was performed using the energy demand pattern of the individual houses in Sapporo, and output change of a solar module and the relation of the operation cost of a system were clarified.
2. The energy network was composed from two or more fuel cell cogeneration, and it investigated about the energy-saving effect at the time of connecting the natural-energy-sources equipments with load fluctuation or output change to this network. In an energy network, each fuel system o

f hydrogen and oxygen of the small fuel cell installed in the house, and exhaust heat and each output system of electric power are connected with piping and a power line to other fuel cells, and operation which cooperated for the purpose of minimization of operation cost is performed. In this study, the analysis method of this system was considered, the energy demand pattern of the individual house in Tokyo was installed, and it applied to the fuel cell network system formed in five buildings.
3. The method of reducing the capacity of a fuel cell facility was proposed with a water electrolysis system. In this system, the water electrolyzer set in the machinery room at the time of low load is operated, compression storage of hydrogen and the oxygen is carried out, these are released to a network at the time of high load, and it generates electricity by a fuel cell. Capacity reduction of the fuel cell equipment was tried by operating such load equalization. Although this method is based also on a load pattern, it is expected that a big effect is in reduction of fuel cell installed capacity. Less
