Energy storage charging pile voltage 7 2

Can private charging piles be supplemented to meet EV charging demands?

With 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 .

Can a grid supplement a shared charging pile?

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.

What are the constraints of shared charging piles?

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.

How is the GNE based on a shared charging pile?

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.

Do all charging pile agents provide sharing services?

In Table 7, though all charging pile agents provide sharing services, the sharing capacity of charging piles provided by different location’s agents varies greatly. The reason is that the sharing revenues of each agent are not the same, so the willingness of agents to participate in sharing service is different.

How is the sharing scheme of private charging piles determined?

The sharing scheme of private charging piles is determined by sharing capacity model based on the generalized Nash game. The quantum particle swarm algorithm with the dynamic feedback mechanism is adopted for a better convergence of the solving process of the hierarchical scheduling model.
