概要 （図表や脚注は「報告書全文」に掲載しております）

近年，エネルギーの効率的な利用や，災害時に一部電力を自給するスマートコミュニティが注目されている。コミュニティが部分最適運用することによる電力系統への影響を評価し，コミュニティとの協調を考えながら電力系統全体を運用する技術を構築するには，経済性の観点からどのようなコミュニティ形態が導入され得るのかを明らかにする必要がある。本報告書では，現状想定される電気料金および託送料金を用いて，コミュニティ内のPV導入率，住宅・商業地域の割合，コミュニティ蓄電池・コジェネの容量をパラメータとして，コミュニティが経済的に成立する条件を検討した。

概要 （英文）

The idea of smart community which is expected to achieve effective utilization of energy at customer side, and contribute to stable operation of power system, for example peak shaving, et. is introduced recently. Since the smart community would optimize the local operation of the community that might affect the stable operation of distribution power system and whole power system, the development of cooperative operation method between community and power system is important. In order to develop the operation method of the community considering cooperation with power system, development of smart community model that is economically feasible is necessary. This report develops the economical evaluation model of smart community for arbitrary condition such as electricity price, purchasing price of generated power of PV, wheeling charge, et. and evaluate the economic efficiency of smart community. According to the evaluation results, a community operator can get benefit by operating community under the condition such as the lower penetration rate of PV, and higher rate of residential area that includes low voltage customers, in which the community operator can sell much electricity with expensive price to low voltage customers. By introducing co-generation system and utilizing exhaust heat for industrial area, the economic efficiency would increase and the community operator can get benefit from dealing with electricity transaction and selling exhaust heat to industrial customer. This paper also considers the Business Continuity Plan (BCP) and evaluates the maximum storage capacity under the condition that the community operator can get benefit, where the battery would be used for back-up power supply when the disaster occurred.
