The paper introduces Distributionally Robust Conformal Safety Screening (DR‑CSS), a policy‑agnostic framework that uses historical data and a nominal simulator to pre‑deploy safety checks for new voltage control policies in active distribution grids. DR‑CSS constructs conformal safety intervals around simulated voltage trajectories, enlarging them to account for closed‑loop effects of the new policy. Experiments on IEEE 33‑bus and 141‑bus systems show that DR‑CSS successfully identifies all unsafe scenarios while adapting intervals to reduce false warnings.

EvEMTBench is an open, executable, and versioned benchmark designed to standardize the evaluation of machine‑learning methods for power system protection. It defines 12 protection and event‑analysis functions across four grids (20–345 kV) as 24 scored tasks, enabling structured assessment under varied observability, distribution shifts, and cross‑grid transfer scenarios. The benchmark includes committed data partitions, leakage controls, and reproducible reporting, and demonstrates that wider observability does not always help, that shifted conditions expose hidden failures, and that fault detection transfers better than fault localization.
