Considering the energy storage cost of energy storage Charging piles, this study chooses a solution with limited total energy storage capacity. Therefore, only a certain amount of electricity can be stored during off-peak periods for use during peak periods. After the energy storage capacity is depleted, the Charging piles still need to use grid electricity to meet the
