Abstract
Hybrid mini-grids usually employ diesel generator sets (gensets) as grid forming units in three-phase four-wire systems. The impact of unbalances in power demand (load) and renewable power injection on the power quality is relatively small due to the also small output impedance of the rotating generators. However, when a battery inverter is required to form the grid, the power quality can deteriorate significantly in the presence of unbalanced power injection/demand in the system, due to the larger impedance of the low-pass output filter. The conventional approach of using three-phase dq control and symmetrical components decomposition (SCD) usually results in slow dynamic response. This paper proposes a per-phase dq technique that does away with the need for SCD and presents superior dynamic performance as demonstrated by simulation.

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
