Grid-connected inverters are key components of distributed generation systems (DGSs) and micro-grids (MGs), because they are effective interfaces for renewable and sustainable distributed energy resources (DERs). Recently, multi-functional grid-connected inverters (MFGCIs) have attracted more...

Micro-grids are effective concepts and systems to interface renewable and sustainable energy resources into utility, which has been paid significant attention. In this paper, the policies and demonstrations of micro-grids for researches and developments, as well as practical applications in...

Microgrid is an effective concept for distributed renewable energies connecting to utility grid. However, enormous challenges have also been brought into the microgrids study considering the intermittence, randomness characteristics of renewable energies. As a result, the power generations of...
