【摘要】：电动汽车充电站或充电设备集群的负荷变化情况受具体车流量、电池充电时长、电池起始荷电状态(state of charge,SOC)、充电设备数量等多种因素的影响,变化规律复杂,各个充电站的负荷曲线形态差异很大,难以从本质上表征负荷的一般性规律。从影响充电负荷变化规律的进站车流量入手,研究电动车辆进站流量、充电时长、充电站充电能力等对充电负荷的具体影响,提出适用于充电站负荷快速计算的简化公式和计及多种影响因素的仿真方法。以西北某市为算例,结果表明,该方法能够方便、有效地预测电动汽车充电负荷的时空分布特性,为分析其对电网的影响及充电设施规划等提供依据。
[Abstract]:The load change of charging station or charging equipment cluster of electric vehicle is affected by many factors, such as specific vehicle flow, battery charging time, battery initial charge state, charging equipment quantity and so on. The load curve of each charging station is very different, so it is difficult to characterize the general law of load essentially. Starting with the incoming traffic flow which affects the changing law of charging load, this paper studies the specific influence on charging load of electric vehicle, such as incoming flow, charging time, charging capacity, etc. A simplified formula for rapid calculation of charging station load and a simulation method taking into account a variety of factors are presented. Taking a northwest city as an example, the results show that this method can effectively predict the space-time distribution characteristics of electric vehicle charging load, and provide the basis for analyzing its influence on power grid and charging facilities planning.
