在未来的交通系统中，电动自主按需移动性（阿莫德）车队的充电行为，即，服务于按需出行请求的电动自动驾驶汽车车队可能会挑战配电网络（PDN），导致过载或电压下降。在这篇文章中，我们表明，如果PDN的操作约束和外源负载（例如，来自家庭或企业）在操作电动阿莫德车队时被考虑。我们专注于系统级的角度来看，假设阿莫德和PDN运营商之间的充分协调。从这个单一实体的角度来看，我们评估潜在的协调效益。具体来说，我们扩展了以前的结果，基于优化的建模方法，电动阿莫德系统，共同控制电动阿莫德车队和一系列的PDN，并分析负载平衡约束下的协调的好处。对于美国加利福尼亚州橙子县的案例研究，我们表明，电动阿莫德车队和PDN之间的协调消除了99%的过载和50%的电压降，电动阿莫德车队将导致在不协调的设置。我们的研究结果表明，协调电动阿莫德和PDN可以帮助保持PDN的可靠性下额外的电动阿莫德充电负载，从而显着减轻或推迟PDN容量升级的需要。
In future transportation systems, the charging behavior of electric autonomous mobility on demand (AMoD) fleets, i.e., fleets of electric self-driving cars that service on-demand trip requests, will likely challenge power distribution networks (PDNs), causing overloads or voltage drops. In this article, we show that these challenges can be significantly attenuated if the PDNs’ operational constraints and exogenous loads (e.g., from homes or businesses) are accounted for when operating an electric AMoD fleet. We focus on a system-level perspective, assuming full coordination between the AMoD and the PDN operators. From this single entity perspective, we assess potential coordination benefits. Specifically, we extend previous results on an optimization-based modeling approach for electric AMoD systems to jointly control an electric AMoD fleet and a series of PDNs, and analyze the benefit of coordination under load balancing constraints. For a case study of Orange County, CA, USA, we show that the coordination between the electric AMoD fleet and the PDNs eliminates 99% of the overloads and 50% of the voltage drops that the electric AMoD fleet would cause in an uncoordinated setting. Our results show that coordinating electric AMoD and PDNs can help maintain the reliability of PDNs under additional electric AMoD charging load, thus significantly mitigating or deferring the need for PDN capacity upgrades.
