Abstract

fetched live from OpenAlex

Optimal power flow (OPF) is one of the important task in the operation and control of electric power system. In this paper, a novel metamodel-based global optimization approach has been proposed and applied to the OPF problems. The approach use limited "expensive" sample data points from the original, computationally expensive optimization model to introduce the surrogate models or metamodels, and to effectively use "cheaper" sample points from the metamodel to speed up the search of global optimum with much reduced computation time and limited number of original model simulations, thereby effectively reducing the calculation amount and greatly improving the efficiency of the optimization search. The simulation verification has been carried out on the IEEE 30-bus test system and by comparing with the conventional population based global optimization methods, the numerical results have shown the effectiveness and feasibility of the proposed method.

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.
