An analysis of large-scale transmission power blackouts from 2005 to 2016
Résumé
Power transmission blackouts, have large technical, economic, and social consequences in the affected areas. As power systems evolve with new customs, technologies and regulations, continuous analysis of recent blackouts is crucial for identifying new trends and for updating prevention measures.
In this paper, we analyze 9 major blackouts that happened between 2005 and 2016, to complete previous blackout studies. We classify these blackouts depending on the conditions and events before and during the cascades and identify their main characteristics. Our analysis reveals that blackouts from the last decade tend to happen in periods of normal loading with some important equipment out of service and with highly dependent transmission system regions. Moreover, recent blackouts show a tendency to enter directly the fast cascade, leaving system operators with hardly any time to take any countermeasure.
