Abstract
In this paper, a control strategy for a distributed generation (DG) unit that provides a seamless transition between grid connected mode and islanded mode is presented. Instead of switching between current control and voltage control modes as commonly proposed in the literature, a voltage control mode is used in both grid connected and standalone modes. The output voltage and frequency are controlled to regulate the reactive and real power injected into the grid, respectively. In the islanded mode, the output voltage and frequency of the DG unit are regulated at their nominal values. Therefore, transition between operation modes is achieved by switching the voltage and frequency references of the same voltage controller. When the grid is interrupted, the DG unit supplies only the load automatically with no abrupt transients in the local load voltage and current, even before the islanding is detected. The principle and implementation of the control strategy to detect the grid conditions and islanding, and to switch seamlessly between the two operating modes are developed. The control strategy is validated through simulations using a detailed switching models in the PSCAD/EMTDC environment.

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
