摘要:

本文利用2013年加州超过2000台非住宅电动汽车供应设备(EVSE)的数据,估计智能电动汽车(EV)充电的潜在效益。我们开发了一个智能充电框架,以确定非住宅EV充电对负荷聚合器和配电网的效益。利用这一大规模数据集,我们旨在改进以往研究,通过放松对驾驶模式、驾驶员行为和驾驶员类型、有限模拟车辆可扩展性以及EV充电曲线的假设。首先,我们研究了在表后聚合的EV效益,使用分时电价了解EV聚合在将负荷从高成本时期转移到低成本时期时对所有者的好处。2013年,我们展示了每月账单可能减少高达24.8%。然后,采用类似聚合策略,我们显示当充电受到达和离开时间控制时,EV聚合可将系统峰值负荷贡献减少约40%。我们的结果还表明,预计可以将约0.25kWh(约2.8%)的能量从峰值时段(12点-6点)转移到非峰值时段(6点后)转移,适用于2013年加州的非住宅EV充电会话。

英文摘要:

In this paper, we use data collected from over 2000 non-residential electric vehicle supply equipments (EVSEs) located in Northern California for the year of 2013 to estimate the potential benefits of smart electric vehicle (EV) charging. We develop a smart charging framework to identify the benefits of non-residential EV charging to the load aggregators and the distribution grid. Using this extensive dataset, we aim to improve upon past studies focusing on the benefits of smart EV charging by relaxing the assumptions made in these studies regarding: (i) driving patterns, driver behavior and driver types; (ii) the scalability of a limited number of simulated vehicles to represent different load aggregation points in the power system with different customer characteristics; and (iii) the charging profile of EVs. First, we study the benefits of EV aggregations behind-the-meter, where a time-of-use pricing schema is used to understand the benefits to the owner when EV aggregations shift load from high cost periods to lower cost periods. For the year of 2013, we show a reduction of up to 24.8% in the monthly bill is possible. Then, following a similar aggregation strategy, we show that EV aggregations decrease their contribution to the system peak load by approximately 40% when charging is controlled within arrival and departure times. Our results also show that it could be expected to shift approximately 0.25kWh (~2.8%) of energy per non-residential EV charging session from peak periods (12PM-6PM) to off-peak periods (after 6PM) in Northern California for the year of 2013.
