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.
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.
According to the taxi trajectory and the photovoltaic output characteristics in the power grid, Reference Shan et al. (2019) realized the matching of charging load and photovoltaic power output by planning fast charging piles, which promoted the consumption of new energy while satisfying the charging demand of EVs.
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 capacity planning of charging piles is restricted by many factors. It not only needs to consider the construction investment cost, but also takes into account the charging demand, vehicle flow, charging price and the impact on the safe operation of the power grid (Bai & Feng, 2022; Campaa et al., 2021).
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.
