Abstract
The business case for MMC-HVDC is becoming popular in power transmission systems. Despite their superior potential compared to the AC and LLC-HVDC technologies, MMC-MTDC grid is yet to be efficiently realised in practice. Operation, control and modelling in such VSC-based schemes are arguably the most challenging research and development problems that academia and industry are presently engaged in. This paper endeavours to review the VSC technology on HVDC applications. Simulation cases of two-terminal symmetrical monopole point-to-point MMC-HVDC that later upgraded to three-terminal radial-configured MMC-HVDC are developed on PSCAD/EMTDC to argue the review and to show the flexibility of MMC-HVDC schemes upon severe transient conditions.

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
