Learn MoreThis new type of charging station further improves the utilization ratio of the new energy system, such as PV, and restrains the randomness and uncertainty of renewable energy generation. Moreover, the PV-BESS can reduce the EV's demand for grid power and the load impact on the grid when the EV is charging.
There have been some studies on the economic benefits of the charging infrastructures. McPhail (2014) explored the technical and economic applicability of energy storage systems coupled with fast charging devices to reduce the cost of charging stations and mitigate the impact on the local grid.
In the daytime, especially at noon, the load change rate is negative. That is the use of photovoltaic and energy storage systems can alleviate the dependence of charging stations on the power grid and reduce the power load on the power grid side. Table 7. Benefits to the charging station, grid and the society. Fig. 11.
Based on the cost-benefit method ( Han et al., 2018), used net present value (NPV) to evaluate the cost and benefit of the PV charging station with the second-use battery energy storage and concluded that using battery energy storage system in PV charging stations will bring higher annual profit margin.
Due to the considerable charging power, the simultaneous charging of a large number of EV charging loads will endanger the safe operation of the power grid. Although time-of-use (TOU) price can alleviate the impact of charging load on the power grid to some extent, it cannot solve the problem fundamentally.
The Photovoltaic–energy storage Charging Station (PV-ES CS) combines the construction of photovoltaic (PV) power generation, battery energy storage system (BESS) and charging stations.
