Abstract
With increasing renewable distributed generation (DG) units connected to utility power grids, deterioration of power quality at the point of common coupling (PCC) becomes a major concern. Power electronic devices in DG units generate harmonics, these harmonics along with harmonics from other nonlinear load in the system might cause excessive harmonic distortion at the PCC. In this paper, an extensive literature review is conducted focusing on harmonic mitigation techniques through advanced control methods for grid-interfacing inverter. Harmonics generated by solar photovoltaic (PV) system are firstly reviewed, potential resonance due to LCL filter is discussed. Then various control methods for harmonics mitigation are reviewed and summarized. This systematic review can facilitate better understanding of harmonics and develop more advanced control schemes to mitigate harmonics in renewable energy system.

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
