Abstract
This paper develops a voltage/frequency regulation scheme for an islanded distributed energy resource (DER) unit. The DER can be either a distributed storage (DS) unit or a dispatchable distributed generation (DG) unit. The DER unit is represented by a (time-varying) DC voltage source that is electronically interfaced to an aggregate of loads. The electronic interface consists of a voltage-sourced converter (VSC) and an LC filter. First, a dynamic model is developed for the DER unit and the loads. Then, based on the dynamic model, a control scheme is designed to regulate the voltage and frequency of the loads. To mitigate the impact of the loads configurations and dynamic properties on the stability and performance of the closed-loop system, a feed-forward compensation has been incorporated into the design. Performance of the DER unit in conjunction with the voltage/frequency controller is evaluated based on digital time-domain simulation studies in the PSCAD/EMTDC software environment. The simulation results verify the effectiveness of the developed control strategy and feed-forward compensation technique.

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
