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.
Based on the flat power load curve in residential areas, the storage charging and discharging plan of energy storage charging piles is solved through the Harris hawk optimization algorithm based on multi-strategy improvement.
During peak time periods, when the remaining capacity of the energy storage system is greater than the set value, its discharging power is the energy storage discharging power. Conversely, the discharging power of the charging pile is supplied by the grid power.
