Abstract
This paper proposes a new framework for the short-term risk assessment of wind-integrated composite power systems via a combination of an analytical approach and a simulation technique. The proposed hybrid framework first employs the area risk method-an analytical approach, to include the detailed reliability models of different components of a power system. In this regard, a novel reliability modeling approach for wind generation for short-term risk assessment is also proposed. Thereafter, a non-sequential Monte-Carlo simulation technique is adopted to calculate the partial risks of the area risk method. As a result, the proposed framework is also capable of including the contingencies and constraints of the transmission system that are customarily neglected in the area risk method. The computational performance of the proposed framework is greatly enhanced by adopting the importance of sampling technique, whose parameters are obtained using the cross entropy optimization. Case studies performed on a modified 24-bus IEEE Reliability Test System validate that the detailed reliability modeling of wind generation and consideration of the transmission system are necessary to obtain more accurate short-term risk indices. Furthermore, the computational performance of the proposed framework is many orders higher than any other comparable methods.

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
