摘　　要：随着能源系统向着绿色低碳化转型发展,大量新型产消者涌入交易市场,给能源交易带来了诸多不确定性,传统的集中式能源交易机制已不能满足新的需求。针对这一问题,本文分析了区块链技术与能源交易模式的契合性,在智能合约的基础上提出并构建了以产消者为研究对象的微电网点对点(peer-to-peer,P2P)能源交易模型,以提高可再生能源的消纳比例;为增加用户收益,使用3种不同出清机制进行结算,并设计了一种用户满意度反馈度量方法,可为后续交易提供参考;通过算例仿真,结果表明出清机制不同程度上影响着用户的满意度与收益,并且点对点能源交易策略优于传统的能源交易策略,该成果为数字化转型背景下创新能源交易模式提供了新的思路。With the transformation of energy systems towards green and low-carbon development,a large number of new prosumers have flooded into the trading market,bringing a lot of uncertainties to the energy trading system.What’s more,the traditional centralized energy trading mechanism can no longer meet the demand.Under the circumstances,this paper analyzes the compatibility of blockchain technology and energy trading mode,proposes and constructs a peerto-peer(P2P)energy trading model for microgrids with prosumers as the research object on the basis of smart contracts,which helps to increase the proportion of renewable energy consumption.In order to increase user’s benefits,three different clearing mechanisms are used for settlement,and a user satisfaction feedback measurement method is designed,which can provide a reference for subsequent transactions.The simulation analysis results show that the clearing mechanism affects the user’s satisfaction and benefits to a varying degree,and that the P2P energy trading strategy outperforms traditional energy trading strategy,which provides a new idea for innovative energy trading mode under the background of digital transformation.
