摘要
规模化电动汽车在充电交易时存在安全性低、自主性差的问题,因此文中提出基于区块链技术的电动汽车充电交易模型。该模型在“多卖方-多买方”的电力市场竞争机制下,利用区块链技术去中心化、安全性高等特点还原电力商品属性,开放用户协商定价的权利。首先制定区块链架构下的电动汽车充电交易框架;其次基于区块链平台与电力市场相似的网络拓扑形态,建立区块链平台下的电动汽车充电交易模型;最后对比传统电力市场、应用区块链平台的电力交易市场下满足电动汽车聚合商需求的充电方案。算例结果证明该模型能满足电动汽车聚合商的个性化需求,提升新能源电厂收益,减少碳排放,为电动汽车充电交易市场提供新思路。
Aiming at the problems with low-safety and poor-autonomy existing in the large-scale electric vehicles(EV)during charging transaction,the EV charging transaction model based on blockchain technology is proposed.Under the competition mechanism of"multi-seller and multi-buyer"in power market,the commodity attributes of electricity are restored and the right of users to negotiate pricing is opened by utilizing the characteristics of blockchain technology for decentralization and high security.Firstly,EV charging transaction framework based on the blockchain architecture is established.And then,based on the similar network topology between the blockchain platform and the electricity market,EV charging transaction model under the blockchain architecture is established.Finally,comparatively analyze the charging schemes that meet the requirements of electric vehicle aggregators in the traditional electricity market and the electricity trading market under the blockchain platform.The results of calculation examples prove that the model established can meet the individual claims of electric vehicle aggregators,increase the revenue of new energy power plants,reduce carbon emissions,and provide a new idea for the electric vehicle charging trading market.
