Energy storage and PV system are optimally sized for extreme fast charging station. Robust optimization is used to account for input data uncertainties. Results show a reduction of 73% in demand charges coupled with grid power imports. Annual savings of 23% and AROI of ∼70% are expected for 20 years planning period.
Note that the demand profiles used in the rest of the paper are obtained with r = 3 charging ports and w = 5 waiting spots. For this analysis, waiting spots are kept the same and only the number of charging ports are changed. With the increasing number of charging ports, BESS power and energy ratings increase.
In addition, the installation of a PV system and a storage system can reduce the PDN peak demand increment caused by charging station operation. Currently, the number of EV charging stations that rely only on the electric grid to recharge EVs is higher than those that are assisted by renewable resources and BESS.
A battery energy storage system (BESS) can act as a power buffer to mitigate the transient impact of the extreme fast charging on the power distribution network (PDN) power quality .
In contrast, with fewer charging ports, more EVs will have to stay in the waiting zones until a port becomes available, and there is a higher possibility of rejection of EV’s charging request, thus decreasing the demand peaks and total area under the charging demand curve.
The charging ports, PV system, and the BESS are tied to a common DC voltage bus , as shown in Fig. 1. This work considers seasonal variations in the solar generation and electricity prices by representing a typical year with four seasons.
