Abstract
Engineers intuit that, as power systems interconnect more and more to exchange large amounts of power over longer transmission lines, wide-area damping control should become increasingly rewarding. However, given the current technological and psychological barriers, decision makers need tools to assess whether the inherent advantages of wide-area control over local control can outweigh the risk incurred by the additional complexity of the underlying telecommunication and SCADA systems. This paper devises a simple small signal analysis-based methodology for pinpointing control sites where wide-area control has a substantial technical advantage over a purely local control. Using a novel fuzzy logic-based PSS scheme applicable to both static var compensators (SVC) and synchronous condensers (SC), the authors first demonstrate the claims of their paper on an interesting three-area power system proposed by Anderson and Farmer. Based on small- and large-signal studies, the findings are then generalized to a large study network from Quebec's provincial ISO, equipped with SVCs and SCs at six and four 735-kV substations respectively, all of them included in the scope of this study. Overall, wide-area control is consistently three to 20 times more efficient technically than the competing local control, depending on the network and the control site.

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
