摘要/Abstract

摘要： 目前配电网中分布式光伏发电渗透率越来越高，利用区块链技术的去中心化、难篡改等特点，有助于分布式发电就地或就近消纳，提高配电网运行的经济性。提出了一种基于区块链的光伏就地消纳交易模式，建立了光伏发电用户和分布式光伏聚合商的效益函数，运用Stackelberg博弈模型确定内部电价，通过边缘计算制定最优用电计划，设计了基于信誉值的就地消纳交易机制，对就地消纳程度低的用户进行惩罚，鼓励用户通过可时移负荷消纳光伏出力。配电网仿真结果表明，在采用区块链的交易模式下，配电网的就地消纳情况得到改善，用户的综合效益得到提升。

Abstract: At present, with the growing penetration rate of distributed photovoltaic generation in distribution networks, the application of blockchain is becoming more appealing to the dispatch of distributed energy transactions thanks to its decentralization feature and tamperproof mechanism. This is particularly beneficial for local or nearby energy consumptions, which can greatly boost the operation economy of the distribution networks. A blockchain-based photovoltaic transaction mechanism is proposed, and the benefit function of photovoltaic users and distributed photovoltaic aggregator is established. The Stackelberg game model is applied to determine the internal electricity price, and edge computing is used to work out an optimal power consumption plan. A reputation-based local consumption transaction mechanism is designed, in which penalties will be imposed on those users with low levels of local consumption. Therefore, users are encouraged to consume more photovoltaic power through time-shifting loads. The simulation of a distribution network shows that the local consumption of photovoltaic power has been improved and the users can benefit more under the transaction mechanism of blockchain.

Key words: photovoltaic trading, Blockchain, edge computing, local consumption, reputation value
