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.
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.
Do energy storage subsidy policies stimulate photovoltaic energy storage integration projects?
The results indicate that, while the current energy storage subsidy policies positively stimulate photovoltaic energy storage integration projects, they exhibit a limited capacity to cover energy storage investment costs, thereby failing to incentivize capital market participation in the construction of such projects.
This 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.
