02 讲座内容

本文研究了一个电车的充电管理问题，主要问题是客户的随机到达以及充电成本在不同时间的差异。作者把该问题建模为随机优化问题，并可以用一种指数锥近似的方法来做。结果显示该方法比saa和dro方法都好。

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.
