Charging pile energy storage system can improve the relationship between power supply and demand. Applying the characteristics of energy storage technology to the charging piles of electric vehicles and optimizing them in conjunction with the power grid can achieve the effect of peak-shaving and valley-filling, which can effectively cut costs.
Electric vehicle charging piles are different from traditional gas stations and are generally installed in public places. The wide deployment of charging pile energy storage systems is of great significance to the development of smart grids. Through the demand side management, the effect of stabilizing grid fluctuations can be achieved.
If it is just to serve the customers of the business districts and the residents of the communities, the AC charging pile is enough to serve consumers and does not need expensive DC charging piles. Therefore, there are many AC charging piles in shopping malls and residential areas, and the land cost is not high.
On the contrary, if it is a newly-built EV charging station, because of the high investment cost of land and construction, AC charging piles only account for a small proportion, and DC charging piles with strong profitability are the main ones. 4.3.2. BEVs and PHEVs
Increases in commercial land prices, which reflect the prosperity of local businesses, have a positive impact on the diffusion of AC charging piles but a negative effect on DC charging piles, which require a higher initial investment and incur higher operating costs.
The promotion effect of direct-current charging piles on EV sales is twice that of alternating-current charging piles in the one-year simulation of our model. Increasing the number of EV charging piles has a significant impact on battery electric vehicle sales but not on plug-in hybrid electric vehicle sales. 1. Introduction
