Abstract
In this paper, a simple and effective strategy is proposed for the coordination of protective devices in typical radial distribution networks embedding distributed generation units. The proposed strategy benefits from microprocessor-based reclosers and directional elements for feeder relays, and addresses the issues of blinding of protection, false tripping, recloserfuse and fuse-fuse miscoordination, and failed auto-reclosing. Another salient feature of the proposed strategy is that it does not require adaptive protective devices. The effectiveness of the proposed algorithm is demonstrated by simulation case studies conducted on a model of an example distribution network, in the PSCAD/EMTDC software environment. The paper also presents the steps taken to characterize the impact of DGs on the protection coordination, for host and neighboring feeders.

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
