Abstract
Voltage source converters (VSCs) are being widely applied in power systems due to the development of renewable energies. The simulation scale of the network is limited by the nonlinearity of VSCs and variable nodal admittance matrix (NAM) due to the switching events. In this letter, a general linearized modeling method with fixed NAM is proposed to realize the efficient modeling of VSCs for real-time simulation. By establishing the state space equations based on the port characteristics of VSCs together with the switching states, a companion circuit with ac and dc sides decoupled is derived by the modified Euler method. Moreover, the proposed model can eliminate the delay between the companion circuit and the global solution of the system, which can effectively improve the simulation accuracy. The performance of the model is validated by real-time simulation and hardware-in-the-loop (HIL) tests for both pulses-enabled and pulses-blocked scenarios.

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
