Their paper addresses a trade-off: fitting the full forecast distribution can underemphasize rare extremes, while heavy tail-weighting can distort that distribution. Stage I models environmental response, load patterns, persistent residual deviations and remaining innovations, then generates joint active- and reactive-power scenarios. Stage II leaves those scenarios fixed and calibrates extreme marginal quantiles using a reference forecast, admitting only outward deviations according to local calibration history and operating state.\n\nIn numerical simulations on FeederBW, the authors report that Stage I outperforms diffusion baselines on energy and variogram scores. Their complete framework reports a 0.1932 active-power 0.99-quantile pinball loss, with a 1.054% exceedance rate against a nominal 1%. On Rolle, they report losses 5.39%–14.40% lower than the active-power-only anchor. They also report that Stage I scenarios have a 0.953 correlation between predicted and observed feeder event rates, with 90.0% of feeder errors within two percentage points.
