摘要
从分析影响电动汽车电力需求的影响因素入手,实地调研电动公交车的充电功率,采用最小二乘法拟合得出公交车充电负荷曲线,利用概率统计方法研究电动私家车充电负荷曲线。以山东电网典型日负荷为算例,研究到2015年、2020年、2030年及不同渗透率下电动汽车接入对电网负荷特性的影响。
From the analysis of the influence factors of electric vehicle power demand, this paper commences with the analysis of charging behavior, utilizing the investigation of the charging power of electric buses. The charging profile of buses is fitted by using Least Square Method. Then the charging profiles of private Electric Vehicles were investigated by way of statistical techniques. Taking the daily load profiles of Shandong electric system in summer for example, studied the effect of electric vehicle access to the power grid load characteristics in 2015, 2020, 2030 and different permeability.
