These problems can be prevented by energy storage systems (ESS). Levelling the power demand of an EV charging plaza by an ESS decreases the required connection power of the plaza and smooths variations in the power it draws from the grid.
The total EV charging energy is 22.3 MWh per station per year. The results show that as the PL and the charging plaza size increase, the relative ESS power and energy requirements and the utilization rate of the ESS decrease. This decrease is faster with low PLs and small plaza sizes and slows down with the increasing PL and charging plaza size.

DC coupled system can monitor ramp rate, solar energy generation and transfer additional energy to battery energy storage. Solar PV array generates low voltage during morning and evening period. If this voltage is below PV inverters threshold voltage, then solar energy generated at these low voltages is lost.
Concurrently, the energy storage system can be discharged at the peak of power consumption, thereby reducing the demand for peak power supply from the power grid, which in turn reduces the required capacity of the distribution transformer; thus, the investment cost for the transformer is minimized.
Energy storage/reuse based on the concept of shared energy storage can fundamentally reduce the configuration capacity, investment, and operational costs for energy storage devices. Accordingly, FESPS are expected to play an important role in the construction of renewable power systems.
