In this paper, we will describe demonstration experiment of P2P electric power trading using block chain conducted in Kanazawa Institute of Technology Hakusan-roku Campus. The P2P trading was experimented by combination of block chain platform developed by The Kansai Electric Power Company and the open platform experimental filed of Kanazawa Institute of Technology. The generation systems are the solar, wind, electric bicycle, stirling engine and thermo-electric with biomass system connected to DC distribution system. In addition, we are also utilizing power from electric vehicle. Two stationary storage batteries are connected to DC systems. The consumers are 8 cottages where many cottages are really inhabited by faculty and staff. The P2P trading was conducted in the fourth quarter in FY2019 and FY2020 using these real data. In the first year, basic verification of P2P trading was conducted such as consistency of trading between sellers and buyers, handling of storage batteries related to renewable energy, and impact of bidding order. In the second year, verification of the use of electric vehicle for P2P transactions was mainly conducted such as reduction of imbalance due to additional bidding and actual power value execution. We will show the details of the P2P trading demonstration experiment and evaluation results.
