Abstract
Distribution static synchronous compensators (DSTATCOMs) are a viable solution for improving power quality in distribution systems, including mitigation for temporary interruptions, voltage dips, harmonics and voltage flicker. Conventional DSTATCOMs are implemented using two cascaded loops, an AC current control loop and a DC-bus voltage loop. This paper proposes an alternative control structure based on the simultaneous control of line current and DC-link voltage by means of instantaneous power control. The instantaneous real and imaginary power calculation is derived and explained. Requirements for flicker and harmonic mitigation are identified. The controller is implemented using two hysteresis comparators and an optimum switching table. The features of the proposed technique are illustrated by means of simulation and experimental results. Advantages include a simple and robust control structure, and better tracking of load fluctuations and/or harmonics.

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
