摘　　要：微电网内分布式可再生能源渗透率的提高导致电能供给的去中心化,电动汽车的随机接入给本地资源配置优化带来机遇与挑战。在这种情况下传统的集中式管理和电力销售不再适用。基于区块链技术,提出了去中心化的微电网电能交易系统框架,设计了用于实现电能交易的链码并清楚阐述了整个交易流程。为了实现资源的最优配置,同时保证参与主体的利益,提出了多阶段的混合拍卖机制。最后,通过超级账本的Fabric网络搭建了一个实际可运行的电能交易平台,结果验证所提交易机制的可行性和有效性。Deep penetration of the distributed renewable energy in the microgrids leads to decentralized power supply. The random access of electric vehicles brings opportunities and challenges to the configuration and optimization of local power resources. In this case, the traditional centralized management and sale of electricity are no longer applicable. Based on the blockchain technology, this paper puts forward a decentralized energy transaction system architecture in the microgrid, designs the chaincode for realizing energy transaction and clearly explains the whole transaction process. A hybrid auction mechanism is proposed to optimize resource allocation and protect user benefits. Finally, this paper builds a practical and operational energy trading platform through the fabric of Hyperledger, and the simulation results show the reliability and effectiveness of the proposed trading mechanism.
