During normal operations, the droop control will control the inverter voltage magnitude and phase angle. However, during short circuit faults, the fault current limiting function will be activated to limit the output current of the inverter. Fig. 4 shows the fault current limiting function.
The P-f droop control also achieves load sharing between grid-forming inverters. The Q-V droop control prevents large circulating reactive power between grid-forming inverters.
Table 1 shows the inverter and controller parameters. 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.
For instance, a novel P-Q-V droop control strategy for interline PV inverter-based distribution networks was proposed in to simultaneously implement active power control (APC) and reactive power control (RPC) to adjust the voltage at the point of common coupling (PCC).
