Abstract
Real-time electromagnetic transient simulation is a powerful tool for the power system transient study and the hardware-in-the-loop (HIL) testing. Large-scale DC grid can meet the flexible transmission requirements with high power efficiency and high controllability. CIGRÉ working group has proposed a DC grid test system, which covers various HVDC configurations and deploys modular multi-level converters (MMCs) in the grid. This work focuses on the efficient solution of the DC grid real-time emulator providing accurate and detailed results. The design and implementation of the CIGRÉ DC grid are carried out on a hybrid MPSoC-FPGA platform realizing the synergy between the Xilinx Vitrex UltraScale+ FPGA device containing a large number of logic resources and Xilinx Zynq UltraScale+ MPSoC device containing the ARM multi-core processing system and FPGA resources on a single chip. Hybrid modeling methodology using device-level electrothermal model, equivalent circuit model, and average value model for the converters is employed to present the detailed device-level results of local equipment and the accurate system-level results of global interactions of the DC grid. The detailed design partitioning and implementation methods are presented, and the real-time results are captured by the oscilloscope and validated with commercial simulation tools PSCAD/EMTDC and SaberRD.

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
