Virtual Resistor Based Harmonic Sharing of DC Active Power Filter in Hybrid AC-DC Microgrid
Bibliographic record
Abstract
DC loads and DC sources are predicted to play an important role in the DC subgrid of the hybrid AC-DC microgrid. However, the low order harmonic in DC subgrid, which are usually caused by AC subgrid, need to be addressed. To mitigate the low order harmonics on DC bus, the DC active power filter (DC APF) is considered to be a promising solution but its harmonic control scheme has to be designed considering that the DC-APFs should be distributed throughout the DC microgrid. This paper proposes a virtual resistor based control strategy which ensures the operation of single DC APF and enables the autonomous harmonic sharing. The design methods of the control parameters, including the controller parameter and the virtual resistor, are given in this paper. Both simulation results and experimental results are provided to validate the parameter design method and the effectiveness of the control method.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
