This paper presents a smart methodology to improve the operation of the power system and to deal with technical issues caused by electric vehicles (EVs) charging demand. Direct-current fast-charging stations (DCFCSs) are indispensable for widespread use of EVs since they can fully charge EVs in a short period of time. The integration of battery energy storage (BES) within the DCFCSs is considered a smart option to prevent the power congestion during the peak hours as well as the grid
reinforcement costs due to DCFCSs. Therefore, the authors proposed a method to determine an optimal size of BES within DCFCSs considering a stochastic modelling approach to predict EV load demand based on the users’ behaviour and the probabilistic driving patterns. In addition, the BES in this paper is used as multifunctional equipment, which is able to provide ancillary services as peak shaving and frequency regulation. Finally, an economic analysis is carried out to evaluate the technical
and economic issues related to BES such as life-cycle costs versus the revenue provided by the transmission system operators (TSOs) for frequency regulation.
