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).
The minimum installation distances for the charging pile are: no less than 700 mm from the back door to the wall, and no less than 500 mm from the side face to the wall. (5) The canopy is built together with the charging pile. (6) This installation method is just a sample for reference.
According to the taxi trajectory and the photovoltaic output characteristics in the power grid, Reference Shan et al.

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.
Based on the proposed dynamic optimization method of time-of-use electricity price, the particle swarm optimization algorithm is used to optimize the charging/discharging behavior of each EV in two stages by establishing a multi-objective function with the maximum charging power and the minimum charging cost.
