Electric vehicle charging piles are different from traditional gas stations and are generally installed in public places. The wide deployment of charging pile energy storage systems is of great significance to the development of smart grids. Through the demand side management, the effect of stabilizing grid fluctuations can be achieved.
As the number of electric vehicles (EVs) increases, EV charging demand is also growing rapidly. In the smart grid environment, there is an urgent need for green charging stations (GCS) to effectively manage the internal photovoltaic (PV), energy storage system (ESS), charging behaviors of EVs and energy transactions with entities.

As the electric vehicle charging pile (bolt) on the power distribution side of the power grid, its structure determines that the characteristics of the automatic communication system are many and scattered measured points, wide coverage, and short communication distance.

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.

In addition, many investigations are highlighted to ensure a better future direction, which can be considered for further research work. Microgrids (MGs) have emerged as a viable solution for consumers consisting of Distributed Energy Resources (DERs) and local loads within a smaller zone that can operate either in an autonomous or grid tide mode.
