    摘要:

    出行温度会通过多方面的干扰直接影响到电动汽车的具体能耗情况,从而导致在不同温度下其充电功率需求的差异。依据统计学原理,在大量样本支撑下,采用最小二乘法获取电动汽车单位公里电耗与出行温度的具体联系,提出一种计及出行温度的电动汽车充电功率计算模型。以北京市某小区配电网为例,采用蒙特卡洛法模拟不同季节(温度)下电动汽车充电负荷的具体差异,分析不同季节下电动汽车负荷对区域电网产生的不同影响,为将来电动汽车充电行为的有序控制提供一种新的分季节调度思路。

    Abstract:

    Travel temperature directly affects the specific energy consumption of electric vehicle through various interferences, resulting in the difference in charging power demand at different temperatures. According to the statistical principle, under the support of a large number of samples, the least squares method to obtain the specific relationship between the electric power consumption per km of electric vehicles and the travel temperatures in this paper. Then a power calculation model for electric vehicles considering the influence of travel temperature is proposed. The distribution network of a certain residential district in Beijing is taken as an example. Monte Carlo method is used to simulate the specific difference of electric vehicle charging load under different seasons (temperatures). The different impacts of EV load on the regional power grid in different seasons are analyzed to provide a new seasonal scheduling idea for the orderly control of EV charging behavior in the future.
