电动汽车共享系统中的车队规模和充电器分配

Fleet Sizing and Charger Allocation in Electric Vehicle Sharing Systems

Yuntian Deng, Abhishek Gupta, Ness B. Shroff

摘要:

在本文中,我们提出了一个封闭的网络模型的性能分析的电动汽车共享系统与一定数量的充电器在每个社区。根据需求分布,我们设计算法来计算最佳车队规模和所需的充电器数量,以最大限度地提高利润,同时保持一定的服务质量。我们发现,利润是凹的车队规模和充电器的数量在每个充电点。如果在城市内安装更多的充电器,我们表明它不仅可以减少车队规模,而且还可以提高城市内所有点的车辆可用性。我们进一步表明,通过模拟,两个慢充电器可能优于一个快速充电器时,充电时间的变化变得相对较大的平均充电时间相比。

英文摘要:

In this paper, we propose a closed queueing network model for performance analysis of electric vehicle sharing systems with a certain number of chargers in each neighborhood. Depending on the demand distribution, we devise algorithms to compute the optimal fleet size and number of chargers required to maximize profit while maintaining a certain quality of service. We show that the profit is concave with respect to the fleet size and the number of chargers at each charging point. If more chargers are installed within the city, we show that it can not only reduce the fleet size, but it also improves the availability of vehicles at all the points within a city. We further show through simulation that two slow chargers may outperform one fast charger when the variance of charging time becomes relatively large in comparison to the mean charging time.
