Abstract
By adjusting V/sub ref/, the voltage reference setting of the DC voltage regulator or the power reference settings P/sub i//sup sp/ of the remaining converter stations, the steady-state DC bus voltages of the voltage-source converter based multi-terminal HVDC system can be made to comply with voltage limits. When any one of the converter stations is lost, over-voltage can destroy a converter station within a fraction of a second. As there is no time to reset the settings, the references must be determined in the very beginning to anticipate the accidental loss of a converter. The paper shows how the well-known voltage sensitivity method and the Lagrange multiplier method are adapted successfully to determine the reference settings for pre- and post-fault 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
