Electricity Decentralized Transaction Framework of Community Energy Internet Cluster Based on Blockchain

The frequent electricity transactions of multienergy complementary Energy Internet Cluster result in higher operating costs and increased risks of information security by traditional transaction mode. Therefore, based on the blockchain technology, this paper proposes an electricity trading architecture suitable for Community Energy Internet Cluster. Firstly, the article elaborates the basic structure of Energy Internet and blockchain, and analyzes the adaptability of blockchain applied to Energy Internet Cluster electricity transaction. Secondly, the process of establishing electricity trading platform and deploying smart contract based on Ethereum network is described in detail. Thirdly, the power transaction framework of Community Energy Internet Cluster is constructed, and the double auction mechanism is applied to complete matchmaking tradeoff, and the smart contract is designed. Finally, a practical energy trading platform is built through the Ganache client of Ethereum network. Case studies demonstrate the feasibility and effectiveness of the trading operation framework.
