Abstract
With the increase in the proportion of new energy sources and the wide distribution of DC loads, DC distribution technology is receiving more and more attention. Based on the research of back-to-back flexible DC transmission HVDC DC transmission technology, a hybrid AC-DC distribution system is derived, through the combination of DC and traditional AC distribution networks, the hybrid AC-DC distribution system can reduce the steps of energy conversion and improve the operational efficiency and power quality. To enhance system power supply reliability and mitigate the randomness and volatility introduced by distributed energy sources, this paper first proposes common topologies for hybrid AC-DC distribution systems. It then applies three reliability analysis methods—the minimum path method, Monte Carlo simulation, and convolution integral method—to perform reliability calculations on several typical distribution system topologies. Finally, using the power supply reliability rates obtained from these methods as evaluation criteria, the Hierarchical Analysis Method is employed to determine the optimal architecture for current hybrid AC-DC distribution systems.

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
