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.
Moreover, our model analyses reveal that, under the condition of low utilization rate of fixed charging piles, the levelized cost of electricity for mobile charging piles is much less. Besides, the land cost also plays a role; when it increases, mobile charging piles could be even more economically competitive.
The simulation results of this paper show that: (1) Enough output power can be provided to meet the design and use requirements of the energy-storage charging pile; (2) the control guidance circuit can meet the requirements of the charging pile; (3) during the switching process of charging pile connection state, the voltage state changes smoothly.
Therefore, the lowest electricity cost 0.4 yuan/kWh is employed for calculation for fixed charging piles, even lower than that of the residential electricity price. Table 1. Input parameters for users’ convenience and expenses.
