What is a photovoltaic-energy storage-integrated charging station (PV-es-I CS)?
As shown in Fig. 1, a photovoltaic-energy storage-integrated charging station (PV-ES-I CS) is a novel component of renewable energy charging infrastructure that combines distributed PV, battery energy storage systems, and EV charging systems.
Why is the integrated photovoltaic-energy storage-charging station underdeveloped?
The coupled photovoltaic-energy storage-charging station (PV-ES-CS) is an important approach of promoting the transition from fossil energy consumption to low-carbon energy use. However, the integrated charging station is underdeveloped. One of the key reasons for this is that there lacks the evaluation of its economic and environmental benefits.
What is the cost-benefit method for PV 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.
What are the advantages of PV-Bess charging station?
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.
What is a PV-es CS charging station?
The charging station is equipped with a PV and energy storage system, which enables the PV-ES CS to purchase electricity from the power grid, and also to transfer the energy back to the power grid. So, the charging facility is complementary to the large power grid.
