电动无人机（E-UAV）技术的出现虽然有些未来主义，但预计将对系统操作提出与电动汽车（EV）类似的挑战。值得注意的是，电动汽车在充电站的途中充电已被认为是电力系统的一种重要类型的灵活负载，这通常对电力系统运营商的电价决策产生不可忽视的影响。同时，基于充电时间和充电价格的充电成本是用户出行成本的一部分，它会影响电动无人机交通对充电站的时空分配。本文旨在研究耦合电力和电动航空运输系统的联合操作，这些系统与中央控制但动态设置中的E-UAV的途中充电相关，即，随时间变化的旅行需求和电力系统基本负荷。动态电动无人机充电分配被用作平滑电力系统负荷的工具。提出了一种联合定价方案，并制定了成本最小化问题，以实现系统的最优性，这样的耦合系统。数值实验进行测试所提出的定价方案，并证明了联合运营的框架的好处。
The emergence of electric unmanned aerial vehicle (E-UAV) technologies, albeit somewhat futuristic, is anticipated to pose similar challenges to the system operation as those of electric vehicles (EVs). Notably, the charging of EVs en-route at charging stations has been recognized as a significant type of flexible load for power systems, which often imposes non-negligible impacts on the power system operator’s decisions on electricity prices. Meanwhile, the charging cost based on charging time and price is part of the trip cost for the users, which can affect the spatio-temporal assignment of E-UAV traffic to charging stations. This paper aims at investigating joint operations of coupled power and electric aviation transportation systems that are associated with en-route charging of E-UAVs in a centrally controlled and yet dynamic setting, i.e., with time-varying travel demand and power system base load. Dynamic E-UAV charging assignment is used as a tool to smooth the power system load. A joint pricing scheme is proposed and a cost minimization problem is formulated to achieve system optimality for such coupled systems. Numerical experiments are performed to test the proposed pricing scheme and demonstrate the benefits of the framework for joint operations.
