To optimize grid operations, concerning energy storage charging piles connected to the grid, the charging load of energy storage is shifted to nighttime to fill in the valley of the grid's baseline load. During peak electricity consumption periods, priority is given to using stored energy for electric vehicle charging.
In terms of variable costs, the capacity and electricity cost of the energy storage battery (ESB) is determined based on the power needed during peak hours, and the electricity cost during non-peak hours is obtained using the arrival rate of electric vehicles during non-peak hours.
In the charging and discharging process of the charging piles in the community, due to the inability to precisely control the charging time periods for users and charging piles, this paper divides a day into 48 time slots, with the control system utilizing a minimum charging and discharging control time of 30 min.
Combining Figs. 10 and 11, it can be observed that, based on the cooperative effect of energy storage, in order to further reduce the discharge load of charging piles during peak hours, the optimized scheduling scheme transfers most of the controllable discharge load to the early morning period, thereby further reducing users' charging costs.
The PV and storage integrated fast charging station now uses flat charge and peak discharge as well as valley charge and peak discharge, which can lower the overall energy cost. For the characteristics of photovoltaic power generation at noon, the charging time of energy storage power station is 03:30 to 05:30 and 13:30 to 16:30, respectively .
Based Eq. , to reduce the charging cost for users and charging piles, an effective charging and discharging load scheduling strategy is implemented by setting the charging and discharging power range for energy storage charging piles during different time periods based on peak and off-peak electricity prices in a certain region.

First of all, we will calculate charging current for 120 Ah battery. As we know that charging current should be 10% of the Ah rating of battery. Therefore, Charging current for 120Ah Battery = 120 Ah x (10 ÷ 100) = 12 Amperes. But due to some losses, we may take 12-14 Amperes for batteries charging purpose instead of 12 Amps. Related Posts
