Abstract
The large-scale integration of distributed energy resources (DERs) reduces system inertia, raising concerns about grid stability. Inverter control can emulate virtual inertia by replicating the behavior of traditional generation units, leading to the concept of virtual synchronous generators (VSGs). However, VSGs face transient stability challenges similar to synchronous generators (SGs) and risk instability during prolonged faults. The damping factor plays a critical role in VSG transient stability, but its impact has not been comprehensively analyzed in existing literature.This paper proposes an adaptive damping strategy that automatically adjusts based on the VSG angle. Simulation studies conducted in PSCAD demonstrate that the proposed strategy: (i) allows VSGs to ride through prolonged faults without losing stability, (ii) effectively damps VSG acceleration during large disturbances, (iii) enhances transient stability through continuous damping adjustments, and (iv) facilitates faster VSG recovery after significant disturbances.

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
