【摘要】

The rise of electric vehicles (EVs) poses a challenge to balancing supply and demand in local power grids. In this paper, we examine the implications of EVs and smart charging to both the planning-level question of optimal battery and grid capacity optimization, and the operational-level question of day-to-day supply and demand balancing. We show that an entire EV fleet can be modelled as a battery with stochastically varying capacity, and in doing so, restrict EV charging decisions as a constraint of arriving and departing vehicles. Additionally, there is a specific manner in which the number of arriving and departing EVs are correlated and we propose a novel uncertainty set that relates them via their length-of-stay distribution. Our numerical experiments illustrate that ignoring this specific nature of the correlation, say using the more traditional way of using second-order moments to define a moments uncertainty set, can lead to solutions that fail to be robust, or fail to even solve. We also illustrate that while EVs do lend a degree of flexibility to power grids, a cost needs to be paid either in terms of compelling customers to commit to the time window that their vehicles are parked, or a higher level of uncertainty to the grid operator should there be variability in this time window. The modelling method that we propose in this paper has the potential to be extended to other situations where optimization is required over an inner sub-problem with scheduling decisions on an uncertain number of entities.
