Abstract

Electric Vehicle (EV) penetration is rapidly increasing across the world and utilization of these in vehicle-to-grid (V2G) services can provide benefits to not just operation costs, but also resilience. To optimize the operation of EVs, as well as other local generation, demand and storage, the concept of microgrids has widely been used in the literature for smart control of local resources. During disruptive events such as microgrid islanding, EVs can act similarly to battery storage to minimize loss of critical loads. In this paper, day-ahead schedules are generated for EV operation in an urban multi-energy microgrid (MEMG) every 15 minutes for a 24-hour period. At each 15-minute timestep, individual EVs are updated based on a rolling EV dispatch strategy and real time data is fed back into the day-ahead schedule. After a predetermined time, an outage causes the microgrid to enter islanded mode. The combined and individual benefits of preventive and corrective control of EVs in increasing resilience is assessed, in addition to a comparison of the value of two novel rolling EV dispatch strategies. Results show that both control strategy and EV dispatch strategy can have a considerable effect on resilience enhancement provided by EVs.
