The P-f droop control ensures that the phase angles of multiple grid-forming inverters are synchronized during normal operations. When two grid-forming inverters operate in parallel under P-f droop control, any disturbance causes an increase in the output power of one inverter. [pdf]
Inverter-based technologies behaviour during power system faults is governed by their control logic and settings. While most inverters inject only positive-sequence current, some also inject negative-sequence current to better control the voltages on the AC side of the inverter. [pdf]
