Abstract
This paper presents an application of Single- Input Fuzzy Logic Controller (SFLC) to determine the control signal of Unified Power Flow Controller (UPFC) for improvement of power system stability. This compensation scheme relevant to Flexible AC Transmission systems (FACTS) technology is used worldwide to improve system dynamic performance. The UPFC is one of the most versatile flexible AC transmission system devices, which can be used to control the active and reactive power flows in a transmission line by injecting a variable voltage in series and reactive current in shunt. The SFLC uses only one input variable which is called as signed distance. The SFLC has many advantages: The total number of rules is greatly reduced compared to existing fuzzy logic controllers (FLC’s), and hence, generation and tuning of control rules are much easier. The proposed control method is applied to Single Machine Infinite Bus (SMIB) System to improve the transient stability.

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
