Purpose• Allows user to investigate flow violations found
in the contingency analysis tool
• Identifies key generators and loads that impact contingency overloads
• Identifies key transmission paths(interfaces) impacted by generators and loads

Calculate Sensitivities
Please note that these values will DECREASE flow on the violating element so a positive number is what you would want for overload mitigation.
