为发挥大规模电动汽车充换电设施的调节能力,运营商通常将其聚合参与车网互动,再将集总功率目标曲线分解为个体充放电计划。然而,现有研究主要聚焦于充电设施,且分解方法易引起个体功率波动。针对上述问题,在更小松弛度、更长剩余时间优先级准则的基础上,提出一种考虑前瞻和再分配机制的集总功率分解方法,通过前瞻周期自适应调整提高计算效率;构建了基于动态电池储备的换电站实时运行策略,采用XGBoost算法预测动力电池储备规模;进而,形成充换电设施联合的集总功率实时分解方法。基于实际数据的仿真结果表明,该方法在10万辆电动汽车接入场景下单步运行时间仅为16.65 s,满足在线控制要求,同时,能够有效降低集总功率分解误差和个体功率波动。
To exploit the adjustable capacity of large-scale electric vehicle (EV) charging and battery swapping facilities
operators typically aggregate them for vehicle-to-grid
and then decompose the aggregate power target curve into individual charging and discharging plans. However
existing research mainly focuses on charging facilities
and the decomposition methods tend to cause fluctuations in individual power. To address the above issues
based on the priority criteria of less laxity and longer remaining processing time
an aggregate power decomposition method considering look-ahead and reassignment mechanisms is proposed
which improves computational efficiency through look-ahead cycle adaptive adjustment. The real-time operation strategies based on dynamic battery reserve are constructed for battery swapping stations
and the XGBoost algorithm is used to predict the scale of power battery reserves. Furthermore
a real-time decomposition method of aggregate power is formed for combined charging and battery swapping facilities. The simulation results based on actual data indicate that the method only takes 16.65 seconds to operate in a single step in the scenario of 100 000 EVs
which meets online control requirements and can effectively reduce the aggregate power decomposition error and individual power fluctuations.
