Abstract
Part I of this paper unveiled various shortcomings of existing fault current limiting (FCL) methods for grid-forming (GFM) inverters. Part II of this paper develops a new FCL method that overcomes these drawbacks. Additionally, the FCL method proposed in this paper follows the strict requirements of recent grid codes for the low-voltage ride-through mode of inverter-based resources (IBRs). This makes the exact response of GFM inverters during faults fully predictable. Such predictability is a prerequisite for the reliable design/setting of protection systems, operation, and planning of power grids with high penetration of IBRs. The paper uses PSCAD simulations to corroborate if the proposed method meets these objectives. It also uses simulation results to compare this new method with existing FCL solutions for GFM inverters.

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
