即使存在柴油尾气和温室气体排放的问题，柴油发动机巴士仍占美国巴士车队的大部分。电动公交车不会产生任何排放，是公交车车队的一种很有前途的绿色替代方案。然而，电动公交车的行驶里程有限，充电过程也很耗时。动态无线充电允许电动公交车在行驶中充电，可以缓解电动公交车的缺点。通过动态无线充电技术，电动公交车可以使用更小的电池进行操作，并可以缩短基站的固定充电时间。为电动公交车系统部署动态无线充电设施的关键设计变量是电池大小和无线充电设施的位置。本文研究了电动公交车系统中无线充电设施的最优选址和电池尺寸的设计问题。开发了一个混合整数线性规划，以最小化总实施成本。该模型以实际公交系统为例进行了验证。结果表明，该模型能较好地解决电动公交车系统动态无线充电设施的优化配置问题。
Diesel engine buses still make up the majority of the bus fleet in the United States, even with the problem of diesel exhaust and greenhouse gas emissions. Electric buses, which generate no emissions, are a promising green alternative for bus fleets. However, electric buses have a limited travel range and a time-consuming recharging process. Dynamic wireless charging, which allows electric buses to charge while traveling, could alleviate the drawbacks of electric buses. With dynamic wireless charging technology, electric buses can operate with smaller batteries, and the stationary recharging time at the base station can be shortened. The key design variables in deploying dynamic wireless charging facilities for an electric bus system are battery size and the location of the wireless charging facilities. This paper addresses the problem of simultaneously selecting the optimal locations for the wireless charging facilities and designing the battery size for an electric bus system. A mixed integer linear program was developed to minimize the total implementation cost. The model was demonstrated with a real-world bus system. The results demonstrate that the proposed model can solve the optimal deployment problem of dynamic wireless charging facilities for an electric bus system.
