Consortium Blockchain-based Decentralized Energy Trading Mechanism for Virtual Power Plant

As a new data structure, blockchain has the characteristics of decentralization, high security and information disclosure, which integrates and innovates a variety of computer technologies. Virtual power plant (VPP) is able to increase the operational flexibility of the energy resources and plays an important role in the aggregation of distributed generation resources. For the problem of scheduling difficulty and low transaction efficiency of VPP, this paper proposes a VPP transaction mechanism based on blockchain, which considers the stability on matching supply and demand and priority of renewables. The consortium blockchain is used to allow qualified users to participate in the energy transaction. A market trading platform for VPP based on peer-to-peer (P2P) network in the environment of Ethereum is designed. The incentive mechanism is added to improve the transaction efficiency and the transaction process of VPPis simulated. It shows that the blockchain-based VPP trading mechanism has excellent economy and traceability.
