Self-Synchronized Universal Droop Controller [PDF]
IEEE Access, 2016 In this paper, a self-synchronization mechanism is embedded into the universal droop controller\ud (UDC), which is applicable to inverters having an impedance angle between −π/2 rad and π/2 rad,\ud to form a self-synchronized UDC (SUDC). Both the voltage loop and the frequency loop of the UDC are\ud modified to facilitate the standalone and grid ...
