Abstract
A new stability constrained optimal power flow technique is proposed in this paper. The proposed methodology accounts for system dynamics through the use of a recently proposed stability index as an additional optimal power flow (OPF) constraint. The technique is developed with the objective of maximizing social benefit in the context of competitive electricity markets. An interior point method (IP) is used to solve the proposed OPF problem, and a 3-bus test system with both supply- and demand-side bidding is used to illustrate its application in electricity markets. The results obtained for the system are compared with respect to results obtained for a previously proposed voltage-stability-constrained OPF technique to demonstrate the effect of oscillatory instabilities on the network and market conditions, in particularly locational marginal prices. A power system stabilizer (PSS) is then introduced in the test system to eliminate the oscillation problems, using the proposed technique to determine the PSS effect on electricity pricing and thus suggest a possible mechanism to price the services provided by this controller.

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
