Abstract

Due to the increasing number of electric vehicles (EVs) and the need for faster charging, EVs fast charging stations (FCSs) has been spreading throughout the electric grid and can cause technical impacts in the electric distribution system due to the power withdraw of up to 350 kW. With that in mind, this paper assesses the FCSs capacity to regulate voltage through local dynamic reactive power compensation. The impacts caused by the operation of FCSs as dynamic reactive power compensators (DRPCs) are studied in a real electric distribution grid with time-series power flow (OpenDSS) together with Python routines. Additionally, the Monte Carlo method is used to model the FCSs load curve and its locations stochastically. At the end of this work, it was found that the operation of FCSs as DRPCs can improve voltage profiles and the power factor at the substation, while reduce technical energy losses.
