摘要

电动汽车(ev)的使用如今变得无处不在。电动汽车与电力分配系统的广泛集成具有双重影响:(1)电动汽车充电时可能会给电力分配系统带来负担;(2)电动汽车可以在需要时使用V2G技术放电电池容量。为了减轻电动汽车在电力需求系统中大规模集成的不利影响,电动汽车可以作为移动储能设备(mesd),通过适当的充电/放电方案在整个电力需求系统中传输电能。本文提出了一种混合整数线性规划(MILP)模型来控制电动汽车的充放电,以提高电动汽车的性能。将电动汽车建模为mesd,并研究其对eds的影响。将该模型应用于33辆公交车的eds和苏福尔斯交通网。结果表明,利用该模型,电动汽车可以有效地进行电能传输,从而缓解电网的拥堵,提高系统的性能。

Electric Vehicles as Mobile Energy Storage Devices to Alleviate Network Congestion
Electric vehicles (EVs) usage is becoming ubiquitous nowadays. Widespread integration of electric vehicles into electric energy distribution systems (EEDSs) has a twofold impact: (1) It may impose a burden on EEDSs when EVs are charging, (2) EVs could discharge their battery capacity using V2G technology when required. To mitigate adverse effects of massive integration of EVs in EEDSs, EVs could be used as mobile energy storage devices (MESDs) to transfer electric energy throughout EEDSs using a proper charging/discharging scheme. In this paper, a mixed integer linear programming (MILP) model is proposed to control charging and discharging of EVs to improve EEDS performance. EVs are modeled as MESDs and their impact on EEDS is investigated. The proposed model is applied to 33-bus EEDS and Sioux Falls Transportation Network (TN). The results show that using this model, EVs could transfer electric energy to mitigate congestion in EEDS lines and improve performance of EEDSs.
