基于区块链的大用户直购交易模式研究

Blockchain-based direct purchase transaction mode for large users

大用户直购电是电力市场改革的重要一环,但随着可再生能源的发展导致供给端呈现出去中心化趋势。区块链作为新兴的分布式数据库技术,在当前能源互联网的建设背景下有着很好的应用前景。文章详细介绍了区块链的技术原理,分析了其在电力交易上的应用价值。从传统直购交易模式特点出发,提出了一种大用户直购电链路框架,结合直购电交易特点对分布式共识机制进行研究改进,完善了交易流程对智能合约进行的功能定义,并从整体系统架构上分析了各个层级的通信协议及交互关系。在实验室环境下分析了该系统在实际应用中的表现,为后续研究提供了思路。

The direct purchase of electricity by large users is an important part of the electricity market reform,and the development of renewable energy has led to a trend of decentralization on the supply side.Blockchain,as an emerging distributed database technology,has a good application prospect in the context of the current energy Internet construction.This paper firstly introduces the technical principles of blockchain in detail,and analyzes its application value in power transactions.Then,based on the characteristics of the traditional direct purchase transaction mode,a framework for the direct purchase of electricity for large users is proposed,combined with the characteristics of the direct purchase of electricity,the distributed consensus mechanism is researched and improved,and the transaction process is improved to define the functions of the smart contract.This paper analyzes the communication protocols and interactions relationship at each level from the perspective of overall system architecture.Finally,the performance of the proposed system in practical application is analyzed in the laboratory environment,and it provides ideas for follow-up research.
