Day-Ahead Operation of EV Charging Station in a Logistics Center Considering Charging Behaviors of Different Types of EVs

Vehicle-to-grid (V2G) of electric vehicles (EVs) can help an EV charging station (EVCS) participate in demand response (DR) to save costs. The EVCS owned by a logistics center is responsible to satisfy the charging demands of logistics EVs and private EVs owned by the staffs. The charging behaviors of the two types of EVs are different and have their own regular pattern, which can be considered to guide operation strategy decision-making for the EVCS. Under time-of-use (TOU) pricing, an optimal day-ahead operation model of the EVCS in the logistics center is proposed in this paper, aiming at minimizing the operation electricity costs. By joining in V2G service, two types of EVs contribute to the cost reduction of the EVCS, with charging behaviors of different types of EVs on weekdays and holidays considered. Case studies are conducted to validate the proposed method and the results show that the proposed method can minimize the costs of the EVCS with charging demands of EVs satisfied.
