Abstract

The penetration of electric vehicles (EVs) has been increasing very quickly in the last few years. EVs can help reduce the dependency on the fossil energy, greenhouse gas emission, and improve energy efficiency. Besides the aforementioned benefits, EVs could also provide extra benefits for the neighborhood level network. This paper present a case study to analyze the potential benefit of using an EV fleet as energy storage in order to cut off and save extra battery packs investments on energy storage. Particularly, the paper provides a Continuous Time Markov Chain (CTMC) based EV fleet total available battery capacity estimation framework dealing with cost savings oriented community energy storage sizing problem. The local fast charging station (FCS) queuing situation and the queuing theory are also considered. Experiment results show that the adoption of EVs could helo significantly reduce the investment on battery storage which could bring significant economic and social benefits.
