In this paper, a distributed hierarchical control is proposed for ac microgrid, which could apply to both grid-connected (GC) mode and islanded (IS) mode as well as mode transitions. The control includes three control levels: 1) the basic droop control is adopted as the primary control; 2) the secon...
