a. Based on the charging parameters provided above and guided by time-of-use electricity pricing, the optimization scheduling system for energy storage charging piles calculated the typical daily load curve changes for a certain neighborhood after applying the ordered charging and discharging optimization scheduling method proposed in this study.
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.
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.
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 .
