Abstract
This paper reports on results of a study whose objectives is to demonstrate that a systematic, yet straightforward method based on well-known system theoretical analysis tools can be applied to select the control loops which improve the inter-area dynamic stability while minimizing the interactions among local and global controllers. Two complementary measures are involved in the measurement and control signals selection: the geometric measures which allow choice of signal pairs maximizing the controllability and observability of inter-area modes, and the singular-value based total interaction measure which focuses on minimizing the interactions between the local or global loops at the inter-area natural frequency. As a practical illustration of the proposed measurements and controllers pairing scheme, the linearized model of a nine areas twenty three generators power system involving nine inter-area modes is used. The results obtained show that communication links between areas may deem necessary on one hand to improve the inter-area modes observability-controllability and on the other hand to reduce the interaction between the control loops at the inter-area natural frequencies. The usefulness of such an analysis in minimizing the number of communication links without degrading the overall control system performance is highlighted.

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
