需要家間P2P電力取引の経済性および耐災害性の潜在的評価

抄録

Peer-to-peer (P2P) electricity transactions among prosumers are attracted attention because of the utilization of surplus power caused by distributed generators such as photovoltaic generation (PV). The geographically and electrically close transaction has a higher potential for not only economic but also supply reliability. Therefore, the author had proposed an ideal transaction method in P2P considering both economic and supply reliability based on the assumption, which whole prosumers in P2P can be coordinated transactions. The optimization in the proposed method aims to maximize profit and index regards stored energy in prosumers when a power outage happened. This paper evaluates the potential performance of economic and supply reliability by P2P transactions among prosumers or consumers from long-term perspectives through yearly simulation with actual household demand and weather data. Moreover, the paper reveals the impact of potential performance characteristics of applicable periods related to supply reliability.
