Abstract
This letter proposes a networked oscillators-based approach to analyze the large-signal stability of inverter-dominated microgrids (MGs). Compared with the conventional methods, the proposed analysis is applicable to islanded MGs with a mix of grid-following (GFL) and grid-forming (GFM) inverters. The equivalent networked oscillator model of such MGs with a general topology is developed, and the system's frequency stability domain is analytically derived. A stability evaluation scheme is proposed accordingly and its effectiveness has been validated on a Controller Hardware-in-the-Loop (C-HIL) testbed for multi-inverter applications.

Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from it
