内容简介:

We study the problem of an electric vehicle charging service provider, which faces (1) stochastic arrival of customers with distinctive arrival and departure times, and energy requirements as well as (2) a total electricity cost including demand charges, costs related to the highest per-period electricity used in a finite horizon. We formulate its problem of scheduling vehicle charging to minimize the expected total cost as a stochastic program (SP which can be solved by exponential cone program (ECP) approximations. We show that our ECP approach outperforms the sample average approximation (SAA) and a DRO approach using a semi-definite program (SDP) on numerical instances calibrated to real data. We then show that our ECP continues to perform well considering practical implementation issues, including a data-driven setting and an adaptive charging environment. Finally, based on the ECP solutions, we also discuss managerial insights for both charging service providers and policymakers.
