Residential cogeneration system with PEFC is expected to become a promising technology as distributed resources of power systems in order to improve energy system efficiency. However, it is important to develop efficient algorithm for operation because the energy demand at each house is largely different every day. In this paper, we propose the operational algorithm and evaluate algorithm from view point of energy conservation and economic index based on the energy demand characteristics. In this algorithm, hot water and electrical demand on the next day is estimated based on the average of the past data. By using actually monitored energy demand data, the simulation results indicate that 1) the larger electrical demand a household has, the more efficient this algorithm become at the point of energy conservation 2) the larger hot water demand a household has, the more efficient this algorithm become at the point of economic index.
