Summary of Results of IEEE CFWG Survey on the Analysis of Cascading Outages Cascading Failure Working Group ofIEEE PES Computer and Analytical Methods Subcommittee (CAMS)Marianna Vaiman, V&R EnergyMilorad Papic, Idaho Power Co.2015 IEEE PES General MeetingJuly 27, 2015 1

IEEE CAMS WG on Cascading Failures 2Initiated during 2007 IEEE PES GM:“To investigate new methods, technologies and tools in order to better understand, predict, mitigate and restore cascading failures. Sponsor technical sessions, tutorial courses, workshops, conferences for effective exchange of information on the state-of-the art, best practices, procedures and strategies.” Chair: Milorad Papic, IPC, USA

2015 IEEE CFWG Survey on Cascading AnalysisCFWG collaborated on conducting the survey with: IEEE Corporate - Strategic Research; North American Transmission Forum (NATF);North American Electric Reliability Corporation (NERC). CFWG would like to give special thanks to: Lesleigh Campanale, IEEE;Ed Ernst, NATF;Mark Lauby, Thomas Burgess and Amir Najafzadeh, NERC;ALL OF THE RESPONDENTS TO THE SURVEY.3

Survey OverviewSurvey was conducted to better understand current industry practices, state-of-the-art, and needs in the area of cascading analysis CFWG collaboratively put together a list of 15 questionsThe survey was anonymousThe survey was distributed by IEEE and NATF; NERC also provided a separate response4

Survey QuestionsHow often is the analysis of cascading outages performed in your organization?In which domain does your organization study cascading events?What are the main objectives for performing cascading outages analysis in your organization?Is there a formal definition of cascading outage used in your organization?Is cascading outage analysis an automated process?Do you analyze cascading outages using steady-state analysis tools?Do you analyze cascading outages using dynamic simulations?Do you use historical outage data in your organization to analyze cascading outages and their consequences?Do you model or take into consideration the probabilities of initiating events ? Do you use the metrics/indicators to assess the effects of cascading outages ? Do you apply mitigation measures to alleviate consequences of cascading outages ? Is determining mitigation measures to alleviate consequences of cascading outages an automated process ? Do you use synchrophasor data for prediction or analysis of system blackouts/cascading outages? Are you satisfied with the currently available tools for analysis of cascading outages ? Are there any computations associated with cascading outages you feel present tools fail to address? 5

What would make you more satisfied/Are there any computations associated with cascading outages you feel present tools fail to address? Dynamic simulation of cascading outages which should include protection system modelingBetter solution algorithms/robust toolsAutomated/optimized mitigation measuresIdentifying and classifying widespread system area limitation versus local area limitationIdentifying and quantifying the risk of complicated cascades and large blackouts in a way that allows these risks to be monitored and mitigatedHaving a screening toolWide area visualization and analysis tools that can identify stress indicators early and help operators take appropriate actions21

CFWG is working on detailed analysis of the resultsWill be submitting a paper on the survey results Thank you to all survey participants and facilitators!22Conclusion
