Abstract
Power electronics technology is becoming an increasingly important aspect of today's power distribution system. It is the key interface to connect distributed energy resource (DER) to the utility and the local loads. With the increased penetration of power electronics based distributed generation (DG) systems, the power quality requirements are becoming more stringent. On the other hand, if controlled and regulated properly, the DG-grid interfacing converters are able to improve the system efficiency and power quality, in addition to the primary function of real power injection. This paper discusses the opportunities for power quality improvement through the DG-grid interfacing converters. While the harmonic voltage compensation is the focus of this paper, a number of other ancillary functions, such as unbalance voltage compensation, voltage sag mitigation and reactive power compensation, can be realized in a similar manner. Two alternative DG control methods, namely current controlled DG and voltage controlled DG, are considered and the associated power quality compensation strategies are developed. Simulation results and experimental results from a three-phase 5 kVA laboratory DG prototype are provided.

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
