Abstract
Probabilistic load flow analysis is an important part of grid design, optimization, and operation due to the uncertainties in the power network for both generation and demand, increasingly so for newly integrated technologies including wind power and plug-in vehicles. A reliable, fast, and robust mathematical method for such analyses is a key requirement to help support widespread integration of these new generation and load sources. Conventional deterministic Monte Carlo analyses, though simple in implementation, becomes too slow as networks become more complex. In this paper, a new cumulant-tensor based method is used to assess power flows. Probability distribution functions and reliability indices are generated as final outputs. Furthermore, general correlation between input random variables is included in the analysis. An illustrative 2-bus network is presented along 24-bus IEEE system as case studies, showing the capabilities and increased reliability of the method.

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
