ABSTRACTThe increasing penetration of renewable energy challenges single‐converter systems to simultaneously provide transient support and rapid response. Hybrid microgrids integrating grid‐forming (GFM) and grid‐following (GFL) converters are thus essential for dual‐high power systems. Existing studies primarily focus on single‐converter stability, neglecting the dynamic interactions between converters operating under different control paradigms. In this study, a scaling‐based equal‐area criterion (EAC) method is first applied to analyze the worst‐case stability impacts of interaction terms. The first integration method then reveals that the additional GFM‐VSC alters the potential energy and damping distribution of the GFL‐VSC while introducing path‐related terms. A novel concept, the dynamic parameter‐dependent domain of attractions (PDAs), is employed to analyze the transient behavior of the GFL‐VSC. The expansion of the PDA indicates that the additional GFM‐VSC enhances the transient stability of the GFL‐VSC by modifying its potential energy and damping distribution. However, the energy released or absorbed by path‐related terms affects the effectiveness of the GFM‐VSC in improving transient stability, which can be mitigated by increasing the inertia coefficient of the GFM‐VSC. Simulation and experimental results are presented to validate the proposed approach and verify the conclusions.
