基于区块链的分布式能源交易关键技术

分布式能源凭借能效高、运行灵活、经济性好等特点，逐渐成为发电的重要来源。区块链技术的去中心化、公开透明等特性与分布式能源的交易需求相吻合，探索基于区块链的分布式能源交易有助于消纳能源，降低信用成本。首先从双方的典型特征方面，分析了区块链技术与分布式交易的契合度；接着介绍了区块链技术在提高交易处理效率方面的新发展，以及结合了区块链技术的分布式能源交易理论研究与实际应用；然后，从点对点(P2P)交易、集合竞价以及连续双边拍卖3个方面，分析了国内外在区块链交易方面的研究现状；最后给出了中国在区块链参与消纳分布式能源、建设需求响应管理等方面的建议。

Key Technologies on Blockchain Based Distributed Energy Transaction

Distributed energy has gradually become an important source of power generation by virtue of its characteristics of high energy efficiency, flexible operation and economy. The decentralization, openness and transparency of blockchain technology are consistent with the transaction demand of distributed energy. Exploring the blockchain based distributed transaction mode can help to promote energy integration and reduce credit costs. Firstly, the fitness of combining blockchain technology and distributed transaction is analyzed from the typical characteristics, and the new development of blockchain technology in improving transaction processing efficiency and its theory and practical application in distributed energy transaction are introduced. Then, the research status of blockchain transaction is analyzed from three aspects of peer-to-peer transaction, call auction and continuous double auction. Finally, suggestions are given on how to promote distributed energy integration and the management of demand response by means of blockchain in China.
