Abstract
This paper presents and compares three voltage stability constrained optimal power flow (VSC-OPF) techniques for both voltage stability improvement and power losses minimization. The techniques are based on static voltage stability indices which provide important information about the proximity of the system to voltage collapse. The first one is a new concept based on the line voltage collapse proximity indicator (VCPI), the second utilizes the bus voltage stability indicator L-index and the last one focuses on the minimum singular value (MSV) of the power flow Jacobian matrix. The approaches are described in detail and evaluated on the IEEE 14-bus and 30-bus test systems, where their performances are compared under different operating conditions.

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
