摘要

电动汽车充电对电力系统的可靠性有着重要影响。约束电网是保证电力系统可靠性的可行方案。然而，在有限的电网条件下，如何平衡额外的负荷对停车场运营商来说是一个挑战。如果尺寸合适，电池的快速和高功率密度使它们成为这项任务的理想选择。提出了一种考虑约束电网中电动汽车间歇性使用的停车场电池容量计算算法。考虑电动汽车的出行方式、充电需求和驾驶员行为，构建了电动汽车的充电模式。该算法避免了电池储能系统尺寸过大/过小的问题，满足了停车场电动汽车的充电需求。以住户出行调查的真实数据和停车占用数据为特征的仿真结果表明了该算法的准确性。

Novel Sizing Method of Energy Storage System Considering Intermittent Usage of EVs in a Constrained Grid

Charging of electric vehicles (EVs) significantly impact the reliability of the power system. A constrained power grid is a feasible solution to maintain the reliability of the power system. However, in a constrained power grid, it is challenging for the parking lot operator to balance the additional load. The fast and high-power density of batteries makes them a conceivable option for this task if adequately sized. A sizing algorithm is proposed to compute the battery capacity for parking lots while considering the intermittent usage of EVs in a constrained grid. Charging profile of EVs is constructed by considering travel pattern, charging need and driver’s behaviour of EVs. The proposed sizing algorithm avoided over/under-sizing of the battery energy storage system and fulfilled the EV charging demand in the parking lot. The accuracy of the proposed battery sizing algorithm is shown by simulation results, characterized by real data of household travel survey and parking occupancy data.
