AC-Side Impedance-Based Stability Assessment in Grid-Forming Modular Multilevel Converters

IEEE Access
Grid-forming converters can emulate the behavior of a synchronous generator through frequency droop control. The stability of grid-forming modular multilevel converters can be studied via the impedance-based stability criterion. This paper presents an ac-
