摘要

随着对环境的重视程度不断提高，越来越多的人选择电动汽车作为出行工具。电动汽车的使用人数越来越多和应用范围越来越广，随之也产生充电时间集中导致电网负担过重，电能质量降低的问题，为此对电价引导下的电动汽车负荷特性进行了研究。通过对电动汽车时空分布特性的研究，制定相关策略以调整用电负荷分布、缓解电网峰值负荷压力，对充电桩的安装位置及数量提供了合理的数据支撑；其次，对比有序充放电与无序充电对电网的影响，分析有序充电的优势所在，及有序放电对于电网"削峰填谷"的积极作用；最后，分析目前市场上现有的电价策略对用户充电行为的影响作用，并提出一种针对电动汽车的新型定价策略，总结当下电动汽车充电行为仍存在的不足和改进方向。

Abstract

With the progress of society and economic development, people have paid more and more attention to the environment, and more and more people choose electric vehicles as their travel tools. More and more people use electric vehicles and their application scope is getting wider and wider, and the problems of concentrated charging time leading to overloaded power grids and reduced power quality have been raised. This article reviews the research methods and results of such problems in the field of electric vehicles. Based on the study of the spatio-temporal distribution characteristics of electric vehicles, formulate relevant strategies to adjust the power load distribution, alleviate the peak load pressure on the power grid, and provide reasonable data support for the installation location and number of charging piles. The impact of sequential charging on the power grid, analyzes the advantages of ordered charging, and the positive effect of ordered discharge on the "peak-cutting and valley-filling" of the power grid. Finally, analyzes the impact of existing electricity price strategies on the market on user charging behavior. A new pricing strategy for electric vehicles is proposed, and the shortcomings and improvement directions of electric vehicle charging behavior are summarized.
