Mode‐adaptive multifunctional control of the distributed generation‐based AC microgrid for seamless grid synchronisation

Abstract This study presents a mode adaptive multifunctional control strategy that avoids the collapse of the microgrid due to the subsequent failure of the generation units and faulty grid. Its control allows the distributed generation‐based AC microgrid consisting of a PV panel, wind generation un...

Its control allows the distributed generation‐based AC microgrid consisting of a PV panel, wind generation unit and battery energy storage to operate seamlessly during utility connected and outage operating modes.

Extended second order generalised integrator‐based frequency locked loop (eSOGI‐FLL) control avoids frequency and phase oscillations and provides the effective frequency and phase synchronisation.
