Abstract
Microgrids composed of grid-following (GFL) and grid-forming (GFM) inverters based on the Andronov-Hopf Oscillator (AHO) are becoming increasingly popular. However, when grid voltage drops, AHO inverters may enter the current-limiting mode, which complicates the synchronization stability. To solve this challenge, this letter establishes a dynamic power angle model to describe the synchronization behavior of the microgrid under current limits. Equivalent power surfaces are defined to analyze the stability mechanism, and the effects of various parameters on the synchronization stability are clarified. Then, a stabilization control strategy is proposed, and the impact of control parameters on the region of attraction (ROA) of the controlled system is analyzed. Finally, hardware-in-the-loop tests are conducted to verify the effectiveness of the proposed analysis and stability enhancement strategy.
