TL;DR for operators A learned optimizer can propose an answer quickly and still be too slow to deploy if every proposal requires expensive hard-constraint correction before use. In dynamic infrastructure, that correction must be repeated as loads, topology, or operating conditions change. AT-SKM-Net attacks the correction cost rather than removing the correction step. On the IEEE 300-bus benchmark, its full AT-SKM-AC configuration reduces reported SKM-layer time from 8.992 ms for T-SKM-Net to 1.233 ms, a 7.29x speedup, while both corrected methods report zero equality and inequality violations at the paper’s stated tolerance. ...

TL;DR for operators A grid operator may see topology, live measurements, and an incident narrative all point to the same diagnosis. The decision is not only whether the answer is correct, but whether the model relied on evidence that the diagnostic task permits it to use. In the study, shortcut incident text produced a mean signed utility effect of +0.062 even though its preregistered engineering importance was zero. The model therefore became more accurate by using evidence that should not have determined the answer. Accuracy and a plausible explanation cannot reveal that divergence on their own. ...

A power outage is not one problem. It is a queue of smaller, uglier problems pretending to be one. Which switches can be closed? Which loads should come back first? Which distributed generators are available? Which lines will overheat if a local microgrid gets too ambitious? Which voltage limits will quietly make the elegant restoration plan unusable? In a control room, these questions arrive together, under time pressure, with the usual helpful accompaniment of incomplete information and operational consequences. ...
