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.
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 .
The research results indicate that during peak hours at the charging station, the probability of electricity consumption exceeding the storage battery's capacity is only 3.562 %. After five years of operation, the charging station has saved 5.6610 % on electricity costs.
Depth of Discharge (DOD) is another essential parameter in energy storage. It represents the percentage of a battery’s total capacity that has been used in a given cycle. For instance, if you discharge a battery from 80% SOC to 70%, the DOD for that cycle is 10%. The higher the DOD, the more energy has been extracted from the battery in that cycle.
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.
This demonstrates that using energy storage facilities at the charging station can effectively alleviate the grid's load during peak electricity consumption. Fig. 8. Daily electricity requirements for electric vehicles during peak hours at charging stations.
