Abstract-The concept of a microgrid is emerging to be a technically viable approach for meeting reliable supply of electricity with increased availability in the presence of large-scale grid disturbances induced by severe weather events, as well to integrate various types of electricity sources and storage devices close to consumer loads. The existing approaches to studying and ensuring the stability of microgrids are largely incapable of providing the structural certainty to promote true plug-and-play operation, particularly with changing network conditions. Thus, there is a need and an opportunity to develop a stability criterion that can truly promote the plug-and-play capabilities of a microgrid. This article proposes a novel stability criterion that uses an impedance matching approach in a microgrid environment. Analytical and simulation results show stability boundaries that can be used in the grid-tied and islanded cases.
