Abstract

fetched live from OpenAlex

Utilities are facing many challenges in planning and operating the power systems. The use of probabilistic planning approach is a beneficial supplement to the existing system planning and operation process. A series of tools has been developed in Manitoba Hydro to provide inputs to high level decision making process including capital project justification, enhancement of transmission asset management, prioritization of transmission asset investment. The applications of the basic concept that has been used in the risk assessment tools are illustrated through the assessment of a potential investment project involving the replacement of a number of breakers in a practical power system. Particularly the evaluation of the breaker replacement project considers the operational constraints, which is an important aspect that needs to be modelled in practical power system reliability assessment.

Full frame distilled prediction

Teacher imitation

Not 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.
