Within this phase, each microgrid meticulously fine-tunes its energy storage charging and discharging strategies with the primary objectives of mitigating power fluctuations, reducing load
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 reduction in microgrid operation costs is directly reflected in the fast/slow charging prices, which greatly reduces the EVs charging cost. Although there are also certain transfer power consumption costs and queuing time costs, the total cost of EVs is reduced by 55.2% compared with scenario 3 and 44.3% compared with scenario 1.
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.
Although the comprehensive operation cost of the microgrid in the upper layer model of scenario 2 is 10.8643 million RMB, an increase of 9.2% compared with scenario 3, the sum of EVs charging cost and microgrid cost is greatly reduced, and social welfare is the largest in all scenarios.
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. Table 8.
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).
