N2 - This letter proposes a networked oscillators-based approach to analyze the large-signal stability of inverter-dominated microgrids (MGs). Compared with the conventional methods, the proposed analysis is applicable to islanded MGs with a mix of grid-following and grid-forming inverters. The equivalent networked oscillator model of such MGs with a general topology is developed, and the system’s frequency stability domain is analytically derived. A stability evaluation scheme is proposed accordingly and its effectiveness has been validated on a controller hardware-in-the-loop testbed for multiinverter applications.
