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

Page 3: Contingency Sensitivity Analysis - PowerWorld · 2016-03-23 · Contingency Sensitivity Analysis Note: Accessing the tool applies the contingency to the case. BO N N E V I L L E PO

Background• Idea of James Wong of BPA

• Validated by Daniel Kuraspediani, David Kleinschmidt and Chris Kulink

of BPA• Version 18 and 19

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.

Sensitivities to LODF/LCDFs

• Shows impact of opening or closing the selected branch on the violation element

• Calculations will not be shown for any outages/closures resulting in an island
