In addition, the impact of EV charging on the grid can be effectively alleviated by the configuration of energy storage systems, so the configuration of energy storage in FCSs has become a future development trend.
It is worth noting that the annual charging benefits of the bi-level model are lower than those of the single-level model because planning more charging stations will reduce the distance and power required to be driven by EV users when charging demand arises, which reduces energy consumption and has some significance in achieving carbon neutrality.
Forecasting energy demand through charging operations is usually based on users’ habit and on historical traffic data related to EVs. Charging start times and duration, the amount of required charge, the state of charge (SOC) of the battery and the type of car are among the main insights characterising user’s habits.
