N-1-1 Contingency Scenario ATC Analysis
The ATC analysis in Simulator can include a set of contingencies defined in the contingency analysis tool during the ATC calculation. The key is getting that list of contingencies defined for the N-1-1 contingencies. Each contingency will have 2 actions defined, which Simulator will evaluate for outages when calculating the sensitivities used for the ATC […]
