电动汽车在减少二氧化碳排放方面意义重大。随着电动汽车数量的不断增加,其对电力系统尤其是对中低压系统影响的研究也成为日趋紧迫的课题。电动汽车充电负荷作为一种随机负荷,其负荷模型受用户用车习惯、电池特性及环境等的影响。以丹麦为背景,考虑用户日常驾车模式及充电模式,对电动汽车充电负荷特性作了初步分析,并将其应用于典型配电系统分析之中。针对存在大量风电的配电系统,采用蒙特卡洛仿真研究了电动汽车在不同普及程度、电价条件和季节下对配电系统的影响。

Electric vehicles（EVs） provide a unique opportunity to reduce carbon dioxide emissions from the transport sector by drawing on renewable resources.As EVs become increasingly popular in the automotive market,the study of its impacts on the low-voltage grid has become increasingly important.The model of EVs is affected by the user,battery characteristics,as well as the environment.Studies are carried out based on the Danish case.A preliminary model on demand is created by integrating the driving pattern and battery charging characteristics.The model is applied to a typical distribution network.Monte Carlo simulation is employed to study the impact of EVs in the presence of wind power considering different pentration levels of EVs,electricity price schemes and seasons.
