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.
By using BSS to manage the charging of EVs, microgrids can mitigate grid congestion issues caused by multiple EVs charging simultaneously. BSS can distribute the charging load intelligently, considering grid constraints and available capacity, to prevent overloading and ensure a reliable power supply to both EVs and other critical loads .
BSS can store excess energy during low-cost periods and discharge it during high-cost periods. By leveraging time-of-use pricing, microgrids can optimize the charging of EVs to align with cheaper electricity rates, resulting in cost savings.
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).
MicroGrids (MGs) are one of the possible alternatives to efficiently include RESs in the main utility grid. An MG is a small-scale power entity which includes local loads, RESs-based distributed energy generation, such as PhotoVoltaic (PV) modules and wind turbines, and Energy Storage Systems (ESSs), e.g., lithium-ion batteries .
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.
