Abstract

Motivated by the recent interests in implementing both grid-forming (GFM) and grid-following (GFL) inverters in the grid, this work studies the stability of such inverter-dominated systems by analyzing the equivalent model using networked oscillators. The equivalent oscillator models for both GFM and GFL inverters are developed, respectively, which characterize the behavior of the electric network of inverters and loads. The synchronization of the networked oscillators is studied. It is proved that such a system has a set of unique and locally stable operating states when it is synchronized. Moreover, a necessary condition for the system to reach synchronization is derived, which provides a large-signal stability assessment for the system. At last, the proposed work is validated using simulation results.
