Abstract

fetched live from OpenAlex

Inverters in a power station (PS) may have different control algorithms and be made by different manufactures. To ensure small-signal stability at different equilibrium points, systematic analyses and design are required. However, analytical small-signal models of each inverter are not available to the PS operator due to intellectual property (IP), which hinders the stability analysis and improvement. To overcome this problem, firstly, a gradient-based black-box modeling technique of the inverter is proposed. The gradient-based black-box model should be provided by the manufactures. Based on it, an optimization method is proposed to improve the stability margin of the PS, which should be completed by the PS operator. Under the given work-flow, the IP rights would not be infringed.

Fetched live from OpenAlex and de-inverted. Abstracts are not stored in this database: the inverted indexes are 8.6 GB of the frame’s 9.3 GB of text, and the host has 13 GB free.

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.
