Abstract

In this paper, the smooth transfer ability of inverter with generalized droop control (GDC) is analyzed. With a well-designed controller, the GDC can achieve satisfactory control performance. Compared with traditional droop control, it can provide virtual inertia and damping properties; therefore, when the grid is broken, the change of frequency of output voltage of inverter with GDC is smoother than that of inverter with droop control. Compared with virtual synchronous generator (VSG) control, although both of them can provide virtual inertia and damping properties, during the reconnection process from SA mode to GC mode, the overshoot and oscillation of grid current of inverter based on GDC is smaller than that of VSG control based inverter. The effectiveness is validated by the simulation and experimental results.
