Abstract
Direct current (DC) transmission is highly regarded for its ability to dynamically decouple AC power systems by segmenting them into disjoint networks. Such configurations lead to more efficient power transfers and better oscillation damping, but necessitate controllers with seemingly heavy communication requirements that rely on wide-area measurement systems. This paper shows that DC-segmented power systems are poset-causal, making them amenable to powerful decentralized control techniques that can substantially reduce their communication needs. Specifically, optimal decentralized control is attainable with communication only between AC subsystems that are directly connected by a DC line. The approach explicitly leverages the implied graph structure of power systems with AC and DC lines. Numerical results demonstrate that the decentralized controller achieves nearly the same performance as the optimal centralized controller.

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
