Abstract
We aim to solve the OPF problem by defining contingency scenarios involved in the optimization problem by means of a SDP relaxation. Contingency scenarios are performed for the IEEE 39-bus system. Contingency analyses are performed by generation and line losses. Contingency scenarios are considered to be possible events. These events may be single contingencies, such as a generation unit failures or transmission line failures, or they may be double contingencies. Transmission line contingencies occur with the loss of critical lines of the transmission grid on the system. After single or multiple contingencies occur, it is required to shed some load, drop or trip the generation, or trip transmission lines for maintaining secure grid operations. In our contingency scenarios, we basically determine the appropriate amount of load to be shed. The SDP based OPF problem is tested for feasible transactions and generation dispatches in the system. if such action is feasible, the global optimal solution of the SDP-based OPF problem is guaranteed. In addition, the impact of worst-case contingency is examined for our test system. The amount of load shedding required is thus obtained.

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
