Based on the Internet of Things technology, the energy storage charging pile management system is designed as a three-layer structure, and its system architecture is shown in Figure 9. The perception layer is energy storage charging pile equipment.
The new energy storage charging pile system for EV is mainly composed of two parts: a power regulation system and a charge and discharge control system. The power regulation system is the energy transmission link between the power grid, the energy storage battery pack, and the battery pack of the EV.
On the one hand, the energy storage charging pile interacts with the battery management system through the CAN bus to manage the whole process of charging.
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.
The user can control the energy storage charging pile device through the mobile terminal and the Web client, and the instructions are sent to the energy storage charging pile device via the NB network. The cloud server provides services for three types of clients.
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.

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.
Power and compatibility The power of a charging pile refers to the maximum amount of electrical energy that can be output per hour, in kW or "kilowatts". AC charging piles are generally divided into 3.5kw, 7KW, 11kw, and 22KW specifications according to power.
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.
How to repair the energy storage charging piles in the microgrid system 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.
When the microgrid's energy generation exceeds all the loads on it, the microgrid can charge its energy storage devices, such as batteries, via a bidirectional AC/DC converter. The use loads (both AC and DC) are connected to a common AC bus (backbone network). Microgrids can also send out (export) energy to the utility power grid.
Batteries can be used to provide ancillary services within a microgrid. Large-scale storage technologies, such as hydro-based or thermal storage, while cheaper for time shifting operations, have high initial costs that make their implementation in smaller and microgrids challenging.
Considering the power interdependence among the microgrids in commercial, office, and residential areas, the fast/slow charging piles are reasonably arranged to guide the EVs to arrange the charging time, charging location, and charging mode reasonably to realize the cross-regional consumption of renewable energy among multi-microgrids.
In commercial/industrial and utility microgrids, soft costs (43% and 24%, respectively) represent significant portion of the total costs per megawatt. Finally, energy storage contributes significantly to the total cost of commercial and community microgrids, which have percentages of 25% and 15%, respectively, of the total costs per megawatt.
By arranging to charge piles of different types and capacities in different microgrid areas and formulating different charging price strategies, it can satisfy the differentiated demands of EVs users, promote EVs users to reduce charging costs through orderly charging, and help the rapid development of electric vehicles.
The reduction in microgrid operation costs is directly reflected in the fast/slow charging prices, which greatly reduces the EVs charging cost. Although there are also certain transfer power consumption costs and queuing time costs, the total cost of EVs is reduced by 55.2% compared with scenario 3 and 44.3% compared with scenario 1.
This paper proposes a microgrid optimization strategy for new energy charging and swapping stations using adaptive multi-agent reinforcement learning, employing deep reinforcement learning methods to achieve coordinated control of new energy output and charging–swapping loads, effectively reducing the fluctuation of new energy grid power.
