摘要：
With the increasing proportion of distributed resources in the distribution network, it has become an important scientific problem how to provide a trading platform with low trust cost and a trading method with high economy for prosumers with dual attributes of source and load. The blockchain platform with distributed characteristics and PoW security mechanism is considered as one of the most suitable tools for energy trading. This paper establishes a P2P transaction mechanism supported by the blockchain technology for market-oriented operations involving prolific prosumers. First, a quantitative model of resources for the prosumers is established. Secondly, the P2P day-ahead contract is proposed. The prosumers use the Lagrangian decoupling principle and the sub-gradient method to solve the energy planning function. During the period, the price update function is used to achieve information interaction on the auxiliary blockchain, which fully protects the user's privacy and security. The final day-ahead transaction results will be stored in the blockchain bill with traceable content. In the P2P real-time contract, all prosumers do P2P energy transactions to conduct possibly existing power deviation based on the VCG (vickrey-clarke-groves) rules that satisfy the incentive compatibility theory. The consensus transaction results are included in the bill, which guarantees to meet the real-time transaction time limit while providing a convenient settlement blockchain token. Finally, the calculation example verifies the validity of the proposed smart contract. © 2021, Power System Technology Press. All right reserved.
