Abstract

fetched live from OpenAlex

Investigates power system voltage stability in the presence of on-load tap-changing (OLTC) transformers. To assess this type of voltage instability, the sensitivity, dV/dn, of a load voltage, V, to a tap position, n, is analyzed to show the following theoretical results: (1) The region of normal control where inverse control action does not occur lies inside the stability region when there exists an equilibrium. This region is presented as O<I<I/sub max/. (2) Even if an equilibrium does not exist, the voltage continues to recover in the region where this condition holds. (3) The operating point I= infinity corresponds to the point of the static bifurcation which is caused by the dynamics of the load at the bus controlled by the OLTC.<<ETX>>

Teacher imitation

Not 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.
