Abstract
Peer to peer (P2P) and blockchain are highly coupled in terms of decentralization and autonomous transactions. This paper designs a P2P power transaction mechanism based on block chain to meet the economic and security requirements of photovoltaic prosumer. Day-ahead and real-time P2P trading mechanism is designed. Fully open P2P trading mode and decentralized electricity price mechanism are adopted in day-ahead market, and P2P pool trading mode and electricity price mechanism based on supply/demand ratio are adopted in real-time market. In addition, smart contract rules based on blockchain Ethereum are designed to ensure safe operation and efficient intelligence on the blockchain platform. Finally, effectiveness and economy Prosumer P2P trading mechanism in IEEE 14-node simulation and verification of the design.
