摘　　要：为了提升产消用户的经济效益,提出了一种基于区块链技术的产消用户端对端电能交易方法。首先,基于以太坊平台的特性,设计了端对端电能交易平台的总体架构;然后,对交易机制进行了细化设计,包括交易竞价及匹配策略、安全校验模型和信誉值评估模型,并基于Shapley值法建立了能源服务商(ESP)的服务费收取模型,明确ESP的合理收益;最后,基于端对端电能交易智能合约的制定原则,设计了一系列功能合约及辅助合约,实现用户在线上报需求、订单自动匹配、费用实时结算与其他个性化功能。基于IDE-Remix平台对智能合约进行部署与仿真,结果验证了所提端对端电能交易方法的可行性和有效性。In order to improve the economic benefits of proconsumers,a P2P(Peer-to-Peer)power trading method for proconsumers based on blockchain technology is proposed.Firstly,based on the characteristics of Ethereum platform,the overall architecture of P2P power trading platform is designed.Then,the trading mechanism is designed in detail,including bidding and matching strategies,security verification model and reputation value evaluation model.The service fee collection model of ESP(Energy Service Provider)is es⁃tablished based on Shapley value method,so as to clarify the reasonable income of ESP.Finally,based on the principle of making smart contracts of P2P power trading,a series of functional contracts and auxiliary contracts are designed to realize online order reporting,automatic order matching,real-time fee settlement and other personalized functions for proconsumers.The IDE-Remix platform is used to deploy and simulate the smart contracts,and the results verify the feasibility and effectiveness of the proposed P2P power trading method.
