We investigated how cogeneration systems with a pressurized phosphoric acid fuel cell should be installed into urban areas from viewpoints of economic, energy saving and environmental protection properties. An optimization approach is adopted to evaluate the planning of installations efficiently. Equipment capacities and maximum utility demands are determined so as to minimize both the annual total cost, the annual primary energy consumption and the annual amounts of CO_2 and NO_x emissions in consideration of operational strategies for energy demand requirements. This problem is considered a multiobjective optimization one, and discrete sets of Pareto optimal solutions are derived numerically by a weighting method. Through numerical studies on the cogeneration systems installed into an office or apartment-house area, trade-off relationships among the economic, energy saving and environmental protection properties are clarified, and the results show that capacities of fuel cells to be installed become large when considering energy-saving and environmental protection properties as the criteria for evaluation.
