Abstract

We analyze how an electric-vehicle aggregator that manages a number of electric-vehicle garages and is in partnership with a distribution system operator can increase the resilience of the distribution system in which it operates. The study is intended to ensure a resilient operation of the distribution system while satisfying the travel demands of electric-vehicle drivers by identifying the optimal energy contents of the electric-vehicle garages and their operation. In case of a contingency, such energy allows partial supply of the load. For our purposes, an electric-vehicle garage is a distributed energy storage system whose power and energy capacities change over time. Our study relies on a stochastic programming model that represents branch-outage contingencies and substation capacity reduction contingencies in the distribution system. We comprehensively analyze two realistic case studies to illustrate the relevance of the proposed model to improve resilience. The contribution of our paper relies on a convex AC representation of the distribution network with electric-vehicle garages, a detailed stochastic programming model, a focus on distribution system resilience, and a comprehensive analysis using electric-vehicle garages for resilience.
