区块链技术在电力交易中的应用与展望

区块链技术作为分布式记账技术，为能源互联网中的多方协作场景提供了信任基础，在能源互联网中的电力交易等领域已有一些应用尝试。首先，文中回顾了区块链技术在电力交易中的理论研究情况，总结了其在分布式能源交易、产权登记、商品溯源、交易信息共享等方面的工程应用现状。然后，基于区块链的应用价值模型和中国电力市场的发展需求，展望了区块链技术在电力批发市场、电力零售市场、分布式发电市场化交易、电力衍生品交易、源荷互动电力交易、市场主体信用评价等中的应用。最后，分析了区块链技术在实际应用中面临的运算性能、存储容量和信任构建等潜在问题，给出了针对性的解决思路。

Application and Prospect of Blockchain Technology in Electricity Trading

As a distributed accounting technology, the blockchain technology provides a trust foundation for multi-party cooperation scenarios in the Energy Internet, and it has some application attempts in the field of electricity trading in the Energy Internet. First, this paper reviews the theoretical research of blockchain technology in electricity trading and summarizes its engineering applications in distributed energy trading, property right registration, commodity traceability and trading information sharing. Then, based on the value model of blockchain application and the development demand of electricity market in China, applications of blockchain technology are prospected in electricity wholesale market, electricity retail market, distributed generation marketization trading, power derivatives trading, electricity trading of source-load interaction, credit evaluation of market participant, etc. Finally, the potential problems of computing performance, storage capacity and trust agency in the practical applications of blockchain technology are analyzed, and the corresponding solutions are proposed.
