摘要
在电价存在波动的电力市场中,蓄电系统能够通过低蓄高发套利.随着近年来电动汽车商业化程度加快,有必要研究电动汽车的蓄电套利价值.介绍电动汽车的主流电池技术,提出小额蓄电系统模型及其最优化运行方式的计算方法,通过算例分析蓄电容量、充放电功率与最大套利价值之间的关系,进而比较了几种电动汽车主流电池技术的套利价值.讨论了在普通配电网与智能配电网条件下,电动汽车蓄电套利价值的异同.
Abstract
In a market where electricity prices are volatile,electricity storage has arbitrage value by charging at lower price and discharge at higher price.As the commercialization of electrical vehicle makes huge developments,it is necessary to study on the arbitrage value of electrical vehicle through electricity storage.This paper firstly introduces the mainstream battery technologies for electrical vehicles,brings forward the model of a small storage system and the calculation of optimized operating mode,and then analyzes the relationship between the maximum arbitrage value and the storage capacity,charging/discharging rate on the basis of case study.Afterwards,the arbitrage values of different battery technologies for electrical vehicles are compared.Finally,the difference between the arbitrage value in the environment of traditional distribution network and the one of intelligent distribution network is discussed.
