Abstract
One of the main issues related to the integration of Distributed Generation (DG) in the utility grid is safety. The protection schemes of distribution systems are usually designed under the assumption that power flows from distribution system to end users. If a fault takes place and a breaker opens, all circuits downstream will be deenergized. However, this is not the case when a DG is used, and it is possible that an Island with power generation and consumption is created, thus raising concerns with respect to equipment and personnel safety. During islanding, a portion of the utility system which contains both load and generation is isolated from the remainder of the system and continues to operate, a condition that is not desirable. Therefore, a DG interfaced with the utility system must be equipped with an anti-islanding scheme to ensure personnel safety and acceptable power quality. Performance of an anti-islanding scheme is usually evaluated by inspecting the corresponding Non Detection Zone (NDZ). It has been reported in past studies that DG's control scheme has an impact on the NDZ. This paper studies the impact of control structure on NDZ is studied in a grid-connected PV system equipped with a feed-forward control scheme.

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
