Abstract
Average-value models (AVMs) of high-frequency switching voltage-source converters (VSCs) are indispensable for fast/efficient simulation of VSC-based power systems. However, in EMT/EMTP-type programs large simulation time-steps cannot be utilized with conventional non-iterative interfacings of AVMs due to numerical inaccuracy/instability as a result of a one-time-step interfacing delay. In this letter, a directly-interfaced AVM has been developed for the VSCs which eliminates the interfacing delay and allows large time-steps. This is achieved by formulating the AVM in the nodal form that is solved simultaneously with the overall network nodal equations. The new proposed model is demonstrated to outperform the existing AVMs of VSCs in terms of accuracy at fairly large time steps.

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
