Abstract
In this paper, the operation of an inertial flywheel storage system based on the permanent magnet synchronous machine (PMSM) is presented.The contribution in this work lies in the optimization of the exchanged power between the storage system and the grid.The related speed reference is determinate from the desired power through a tracking algorithm known as reference power point tracking (RPPT).This one permit to achieve a desired grid-side power.That is ensured by a simple algorithm which needs only the measurements of grid-side power and reference power.This algorithm is robust because it doesn't depend to system parameters, and to an increased reliability.The problem of variable losses once several grid connected-storage systems are considered is then avoided.This will serve grid operator to adjust efficiently the grid frequency.The last point is the main advantage of the proposed method compared with others ones that use machine-side power measurements for speed reference synthetizing.The studied system is implemented under DSPACE type RTI1005.The rotation speed of the permanent magnet machine and the power exchanged between the electrical grid and the inertial storage system follow their reference with an error of 0.032% and 0.83% respectively.The simulation and experimental results presented show the effectiveness of the tracking algorithm.

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 itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
