A post-contingency power flow emulator for generalized probabilistic risks assessment of power grids
Abstract: Highlights•A risk assessment emulator for power grids overload risk assessment is proposed.•The emulator is embedded within a generalized uncertainty quantification framework.•Line-Outage Distribution Factors efficiently approximate post-contingency severity evaluations.•Archiving 2 orders of magnitudes time-cost reduction with a modest accuracy loss.•Sensitivity analysis via pinching revealed the key inputs driving the imprecision in the risk score.
