The 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.
