Why do inverters inject reactive power if grid voltage is unbalanced?
Furthermore, under unbalanced grid voltage conditions, the inverter should inject reactive power to provide voltage support at PCC, the point of common coupling. Hence, the inverter is used to inject reactive power in an appropriate amount. The grid code prescribes this amount, based on as to how severe is the dip in the grid voltage.

What happens if PV capacity is less than base station load?
When the installed PV capacity is less than the base station's daily load, the return on investment of PVs remains relatively stable, but it gradually decreases as the installed PV capacity increases. The return on investment of adding ESS is consistently lower than that of PVs, but its trend is different.
