摘　　要：在微电网中利用区块链技术实现分布式电能的直接交易已成为研究热点。然而,光伏发电的间接性和波动性以及电动汽车的随机接入驶离给交易带来巨大不确定性。为此,提出一种基于合约订单的分布式电能交易模型。该模型中用户的匹配交易均通过合约订单实现,在交易中合约订单可以被转让给其他产消者以减少违约场景造成的经济损失。此外,为了解决匹配过程中可能存在的订单冲突,建立了基于最大目标函数和信誉值的冲突解决机制。最后,仿真结果表明,该交易模型在运行效率和经济福利方面均具有可行性和有效性。Using blockchain technology in microgrids to achieve direct trading electrical energy has been heatedly studied recently.However,due to the indirectness and volatility of photovoltaic power generation as well as the random access and departure of electric vehicles,there exist great uncertainties during the transaction.Therefore,in this paper,an order-based distributed energy trading model is proposed,in which user matching and transacting are realized through contract orders.Contract orders can be transferred to other prosumers in transactions so as to reduce the financial losses resulted from default scenarios.In addition,when dealing with possible conflicts during the matching process,a conflict resolution mechanism based on the maximum objective function and reputation value is established.Finally,simulation results turn out that the transaction model is feasible and effective in terms of its operational efficiency and economic welfare.
