Intertied ac–ac microgrids offer many potential benefits like flexible frequency and voltage selection, reserve sharing and enhanced supply reliability. Operating them is however challenging due to their larger size and presence of more power converters with different responsibilities. These complexities can further be amplified when reliance on fast communication links is not permitted. To address these concerns, a new autonomous droop scheme is proposed here for managing intertied microgrids in either the islanded or grid-connected mode. The scheme prioritizes various power generation/transfer responsibilities among power converters found in the intertied microgrids. The objective is to smoothly maximize the overall power handling capability of the intertied microgrids without relying on fast communication links. The proposed scheme has been tested experimentally in the laboratory. [ABSTRACT FROM AUTHOR]
