2015 Tutorial “Understanding Cascading Phenomenon”

IEEE PES GM 2015 Tutorial “Understanding Cascading Phenomenon: Methodologies and Industry Practice for Analysis of Cascading Failures”

Date: July 29, 2015

Tutorial Overview: Cascading failures present severe threats to power grid reliability and security, and thus reducing their likelihood, and timely detection, mitigation and prevention of cascades are of significant importance, and believed to be one of the greatest challenges in power grids today. This tutorial developed by the IEEE Cascading Failure Working Group provides an overview of the cascading phenomenon and explains methods, technologies, and tools that are currently being used to predict, detect, mitigate and restore from cascading failures. This is the first PES GM tutorial dedicated solely to the subject of cascading outages.

This full day tutorial covers the power system cascading concepts, models, relevant standards and existing industry practices for analysis of cascading failures in planning and operating environments. Close attention is given to the new technologies, such as synchrophasor technology, for better detection and mitigation of cascading outages. The tutorial also explains the root causes and mechanisms of propagation of the past blackouts, and discusses the lessons learned. The tutorial, taught by well recognized experts from industry and academia, is intended for power system engineers, regulators, transmission owners, power engineering students and academics. Topics include:

  • Overview of Cascading Outages Phenomenon
  • Framework for Analysis of Cascading Outages
  • Current Tools and Emerging Technologies for Prediction and Detection of Cascading Outages
  • Current Tools and Emerging Technologies for Prevention and Mitigation of Cascading Outages
  • Industry Experience in the Analysis of Cascading Outages
  • Restoration from Cascading Failures
  • Analysis of Past Blackouts Caused by Cascading Outages: Lessons Learned
