Abstract

fetched live from OpenAlex

It is not revealing a secret to say that most of the power system studies highly depend on power flow (PF) analysis. This tool provides a frozen picture of dynamic electric networks under certain conditions. Nowadays, many iterative techniques are available to solve PF problems. The most popular one is built based on the Newton-Raphson (NR) algorithm. Although NR can obtain highly accurate solutions, its processing speed significantly decreases as the problem dimension increases. Thus, a wise selection should be taken to compromise between the processing speed and the solution accuracy. For some critical studies, such as contingency analysis, the processing speed is a very important factor that forces some energy management systems (EMS) to apply DC and AC-DC approximations. This paper studies the processing speed when artificial neural networks (ANNs) are adopted to solve PF problems. First, the standard 9-bus test system is used. Then, the processing speed of ANNs is examined through a very large virtual network. This AI-based technique can hit multiple birds with one stone. Adding to the processing speed and the solution accuracy, it can also solve the uncertainty issue by feeding ANNs with actual PF readings measured from some mounted instrument devices.

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.
