| 中文摘要: |
| 智能合约以信息化方式实现自动验证执行，可实现点对点的、无需第三方信任机制的分布式交易。在高比例可再生能源接入的微网中，利用智能合约搭建分布式交易平台，可提高局部地区的交易效率。首先，构建能源微市场的市场架构，提出了无需中心机构参与的微网电力交易机制：微市场中的购售电服务商确定价格边界，市场成员根据能量管理的结果在市场中发出购售电请求，建立了通过分布式交易所获得的机会收益模型，并提出了给予一定观察时间以优化交易结果的多轮随机匹配机制；其次，基于区块链技术从成员准入、合约创建、共识机制、传播执行等方面详述了智能合约的部署过程；最后通过算例分析验证了所提运营机制的有效性，并证明了局部的高效电力交易可促进可再生能源的就地消纳。 |

| Smart contracts implement automatic verificationexecution in an information based manner, enabling peer to peer distributed transactions that do not require third party trust mecha nisms. In the micro network with high proportion of renewable energy access, the use of smart contracts to build a distributed trading platform can improve the transaction efficiency of local areas. Firstly, the energy micro market structure is built and a micro grid power trading mechanism without the participation of central institutions is proposed：micro market purchase and sale of electricity service providers determine the price boundary, market participants issue a purchase request to sell electricity in the market based on the results of energy management, and establish opportunities for gains obtained by the model of distributed trading. A certain observation time is given to optimize the trading by multiple rounds of random matching mechanism. Secondly, based on block chain technology,the deployment process of smart contracts is detailed from the as pects of member access, contract creation, consensus mechanism,and dissemination execution.Finally, the effectiveness of the proposed operational mechanism is verified by a case study, and it is proved that local high efficiency power trading can promote the local consumption of renewable energy. |
