A two-layer optimal configuration model of fast/slow charging piles between multiple microgrids is proposed, which makes the output of new energy sources such as wind power and photovoltaic in the microgrid match the EVs charging load, thus inhibiting the phenomenon that the EVs aggregation charging leads to the steep increase of grid climbing.
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.
However, the cost performance of energy storage systems is currently low and it has a limited operating cycle, so under the condition of stable operation of the microgrid, it is of great significance to reasonably configure and optimize the energy storage capacity .
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.
Therefore, the proposed two-layer model realizes the optimal configuration of fast/slow charging piles in multi-microgrid areas, effectively reduces the EVs charging cost, reduces the impact of the EVs charging load on microgrids, improves the operation safety of microgrids, and increases social welfare.

1V and an amp-hour rating of 3,500mAh, its energy capacity would be: Energy Capacity (Wh) = 11. most energy storage devices have a large limitation with regards to their usable life--this.
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.
AC charging piles are generally divided into 3.5kw, 7KW, 11kw, and 22KW specifications according to power. The more precise definition of the 7KW specification is 220V/32A/7kw, which is also the most common specification at present. Charging piles above 7kw require a 380V meter.
Charging piles above 7kw require a 380V meter. As mentioned above, the choice should be based on the power of the vehicle's own charger, while considering expansion needs such as changing vehicles. The mainstream new energy vehicle brands now all support 7KW charging piles.
Therefore, the AC charging pile can be understood as a set of connection and control equipment with a protection system. It implements a unified electrical protocol (national standard regulations) to communicate with the on-board charger to achieve functions such as opening and closing the scheduled charging.
Information display screen Some charging piles are equipped with information display screens, which can display information such as voltage, current, real-time power, temperature, charging time, etc. Some can also display the working status of each phase of the three-phase charging pile.
So if you have two cars at home, or consider future expansion, you can consider choosing a 22KW charging pile. In short, you must choose a charging pile that is not less than the power of the on-board charger and is compatible. Note that charging piles above 7kw require a 380V meter.
