Distributed Unbalanced Voltage Suppression in Bipolar DC Microgrids with Smart Loads
Bibliographic record
Abstract
Bipolar DC microgrids (BDC-MGs) have been developed to improve the performance of conventional DC microgrids (DC-MGs). Voltage unbalances between the positive and negative poles, however, reduce system efficiency, make power flow control more complex, and create issues in hybrid AC-DC microgrids. In general, centralized and distributed approaches are proposed in the literature in order to address the voltage unbalance issues in BDC-MGs. Distributed approaches are more robust against a single point of failure and more scalable than centralized solutions. This paper proposes a new distributed voltage balancing method for BDC-MGs with three-wire loads that are operated as smart loads in BDC-MGs. This method relies on the unused capacity of three-wire power electronic converters in the DC-MGs so that no additional converter is required. The proposed voltage balancing method’s feasibility is confirmed with simulation results obtained from MATLAB/Simulink.

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.
