Graphical Ways to Visualize Operational Risk Results for Transmission System Contingencies

The increased complexity of the transmission grid can endanger operational security grid. Operational risk assessment, a stochastic tool, helps to enhance security. Contingency analysis and its impact quantification are main constituents assessment. In this study, different graphical methods proposed visualize contingency-based detailed results: heat-map risk-based contingency chart. Through heat-map, system operator determine which contingencies contribute most would therefore be threatening for “risk-based chart” allows analyze cases from probability aspect in one Both tools may used control room improved planning. study various types network studies severity factor quantification, IEEE 39-Bus sample is Power-Factory behavior under scenarios.
