Can droop control inverters be connected in parallel?

Through the above theoretical analysis, we found that when the inverters based on the traditional droop control strategy are connected in parallel, there will be circulating current and uneven reactive power distribution problems caused by unequal line impedances.

What are the Droop characteristics of the inverter control?

Droop Control: The Figure shows the droop characteristics of the inverter control. The droop P/F is set to 1%, meaning that microgrid frequency is allowed to vary from 60.3 Hz (inverter produces no active power) to 59.7 Hz (inverter produces its nominal active power).

Do droop control inverters need PLL?

With the droop control technique, PLL are not required to achieve system-wide synchronization because all inverters reach the same frequency. In addition, power sharing among each inverter can be achieved since each inverter gives power in proportion to its capacity.
