Abstract
This article presents a magnetic amplifier-based power flow controller as a new approach to control power flow based on a magnetically saturated reactor concept. The magnetic amplifier-based power flow controller uses the magnetic field as control medium to decrease the operating energy losses and increase system reliability. By providing continuous impedance, the magnetic amplifier-based power flow controller can suppress the inter-area oscillation and improve the system stability. A model of magnetic amplifier-based power flow controller is built and verified by lab experiments. A control strategy implementing the magnetic amplifier-based power flow controller is proposed to demonstrate the application of this new device to damp low-frequency oscillation in an interconnected power system. A comparative analysis of the controller's performance is carried out and incorporated with various input signals and multiple loading conditions. The simulations are conducted by power systems CAD (PSCAD, Manitoba Hydro International Ltd., Winnipeg, Canada). The results show the effectiveness of the controller in damping inter-area oscillations.

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
