【摘要】：针对电动汽车的充电特性,本文以实测充电数据为基础,拟合其五阶高斯充电分布规律,在此基础上研究了多场景下含电动汽车的配网电压稳定裕度,分析采用无序充电和峰谷分时电价调控充电方式时,不同渗透率的电动汽车充电对配电网电压稳定裕度造成不同程度的影响,以及电动汽车以不同比例接入充电站节点时对配网电压稳定裕度的影响,并依据系统电压稳定裕度采用一种可切负荷控制策略,以提高系统应对电压失稳能力。
[Abstract]:In view of the charging characteristics of electric vehicles, based on the measured charging data, this paper fits the five order Gauss charge distribution law. On this basis, the voltage stability margin of the electric vehicle with multiple scenes is studied. The charge matching of electric vehicles with different permeability with different permeability is analyzed when disordered charging and peak valley time price regulation and charge mode are used. The voltage stability margin of the power grid has a different degree of influence, as well as the influence on the voltage stability margin of the distribution network when the electric vehicle is connected to the charging station in different proportions, and a tangent load control strategy is adopted to improve the system's ability to cope with the voltage instability according to the system voltage stability margin.
