Currently, new energy vehicle charging piles are manual charging piles. Due to the fixed location of the charging piles and the limited length of the charging cables, manual charging piles can only provide charging services for the vehicles to be charged in the nearest two parking spaces at most.
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.
If the number of charging piles is greatly increased, the power system will inevitably need to be expanded, which will be costly. The investment cost of charging stations is high and the equipment utilization rate is low, resulting in a waste of charging resources.
