AI Customer ServiceWith the market-oriented reform of grid, it's possible to supplement private charging piles to meet the excessive charging demands of EVs . Shared charging means that private charging pile owners give the usufruct of charging piles to grid during the idle period .
When establishing a charging station with integrated PV and energy storage in order to meet the charging demand of EVs while avoiding unreasonable investment and maximizing the economic benefits of the charging station, this requires full consideration of the capacity configuration of the PV, ESS, and charging stations.
Then, grid can supplement shared charging piles to relieve the power supply pressure of charging stations during the peak charging periods. For private charging pile owners, the main purpose of shared charging is to increase the revenue of sharing.
The results provide a reference for policymakers and charging facility operators. In this study, an evaluation framework for retrofitting traditional electric vehicle charging stations (EVCSs) into photovoltaic-energy storage-integrated charging stations (PV-ES-I CSs) to improve green and low-carbon energy supply systems is proposed.
The existence and uniqueness of the GNE are proved by VI. The solution of GNE is obtained by smooth Newton method. Based on this, a hierarchical scheduling model considering shared charging piles is proposed, which coordinates charging stations and shared charging piles to determine the optimal charging time and location of EVs.
The (44), (46), (47), (48) respectively represent the constraints of regional capacity, fast and slow charging capacity of charging stations and the capacity of shared charging piles. Constraint (49) ensures that the utilization rate of shared charging piles is positive.
