Abstract
Private electric vehicles (EVs) have great potential to conduct emergency power supply, considering the rapid development of EVs and vehicle-to-building (V2B) technologies. To enhance the resilience of the building power supply, charging piles can be upgraded to support bi-directional power supply, thus enabling EVs to help restore the buildings affected by disasters. A planning method for the charging piles’ upgrade is proposed. First, a scenario set is generated to consider the influence of uncertainties during the planning period. The uncertainties of disasters, EVs, and building load are included. Then, a two-stage stochastic programming model is established to decide the upgrade plan. Pre-disaster decisions are made in the first stage and the building is restored in the second stage. The method is applied to two different types of buildings and the test results verify the effectiveness of the proposed method.
