Integrated framework for dynamic security analysis

This paper describes an integrated framework for power system dynamic security analysis in both online and the offline modes. In the online mode, the framework allows for the use of efficient techniques for the pre-selection screening and ranking of contingencies and the calculation of relevant operating limits. In the offline mode, this framework can help the operations planner by: providing a friendly graphical user interface; guiding a systematic progression in the decision making process; preparing relevant combinations of available options and adverse power system operating conditions; minimizing inadvertant omissions; performing routine data manipulation; archiving and retrieving information; checking the input data for completeness, consistency and reasonability; and organizing the output results from various cases
