摘要
当前电动汽车负荷时空分布预测研究主要侧重于充电负荷,而对V2G放电能力的预测考虑较少。为此,本文从交通规划的角度进行考虑,提出了一种电动汽车V2G放电负荷时空分布预测方法。以城市停车需求预测模型为基础,分析了工商业区和居住区内电动汽车在时空上的停放分布特性,建立了电动汽车V2G负荷容量模型,并给出了基于蒙特卡洛模拟的预测方法。最后以某城市为算例进行了仿真,分析了工商业区和居住区电动汽车的V2G负荷特性,以及备用行驶容量、充放电功率和日均行驶里程对V2G放电能力的影响。
Currently, the research on V2 G load temporal and spatial distribution forecast mainly focuses on charging load, with less consideration for discharging. A V2 G discharging load temporal and spatial distribution forecast method is proposed, from the aspect of traffic planning. Based on city parking demand model, parking characteristics of EVs in industrial/commercial and residential areas are analyzed and V2 G load capacity model is built. Also, forecast method based on Monte Carlo simulation is given. Finally, taking a city for a computing example, V2 G load characteristics in industrial/commercial and residential areas are analyzed. Meanwhile, it is given how V2 G load is impacted by reserve driving capacity, charging and discharging power, and daily average driving range.
