区块链技术在虚拟电厂交易中的应用综述

Review of the Application of Blockchain Technology in Virtual Power Plant Transactions

区块链技术自提出以来被应用到各行各业中,因其透明安全的交易环境以及共同维护的节点信息被人们应用到虚拟电厂(virtual power plant, VPP)中,满足VPP聚合各类分布式能源,构建以清洁低碳能源为主体的能源供应体系以及电力系统安全运行和综合防御体系。从区块链与VPP的概念出发,对共识机制、加密技术、分布式存储以及智能合约四个方面在VPP的适用性与应用场景进行了分析。最后对区块链在VPP应用中遇到的问题进行分类总结,旨在提升VPP与分布式电源交易的灵活性以及数据管理的安全性,为VPP与区块链进一步结合优化电力市场结构提供了思路。

Blockchain technology has been applied to all walks of life since it was proposed.Because of its transparent and secure transaction environment and jointly maintained node information,it has been applied to virtual power plants(VPP)to meet the needs of VPP aggregation of various distributions.The flexible application of the energy supply system with clean and low-carbon energy as the main body,as well as the safe operation and comprehensive defense system of the power system.Starting from the concepts of blockchain and VPP,this paper analyzes the applicability and scenarios of VPP in four aspects:consensus mechanism,encryption technology,distributed storage and smart contracts,and finally analyzes the application of blockchain in VPP applications.The problems encountered are classified and summarized,aiming to improve the flexibility of VPP and distributed power transactions and the portability of data management,and provide ideas for further combining VPP and blockchain to optimize the structure of the power market.
