摘要
首先建立了电动汽车各类充电设施负荷的基于概率分布的数学模型,并结合河南实际情况确定了仿真计算的设置条件和模型参数,进而确定了概率密度分布函数和累积分布函数,通过对河南省电网进行负荷预测得到基础负荷曲线,并对各类充电设施进行负荷预测得到充电负荷附加需求曲线,将基础负荷曲线及充电负荷附加需求曲线进行峰谷叠加,研究了不同发展阶段充电设施对河南电网负荷特性的影响,分析充电负荷与电网的适应性,为充电设施建设及充电管理提出相应建议。
This paper establishes probalility de nsity distribution load characteristic model of various electric vehicle charging equipment,through confirming calculation setting condition and model characteristic ,detrudes probability density distribution function and cumulating distribution function. The basic load curve described by Henan Grid load forecast and additional demanding curve described by charging load forecast are peak-valley superimposed, and the influence on Henan Grid from charging load of electric vehicle with different ages is studied and the adaptability between charging load and electric network is analyzed.Finally,this paper puts forward suggestions about charging equipments construction and management.
