electric transmission system

“Resilience and Stability of Ecological Systems” was a paper by the Canadian ecologist C.J. Hollings published in the Annual Review of Ecology and Systematics 1973. The concept of resilience was used to describe the persistence of natural systems in face of changes in the ecosystem. The paper has had a major impact within ecology and the concept of resilience has later been expanded to many other areas, including the electric grid.

The 2003 Northeast blackout and extreme weather events like hurricane Katrina (2005), superstorm Sandy (2012), polar vortex (2014), hurricanes Harvey, Irma and Maria (2017), as well as awareness of new risks, such as physical and cyber-attacks, etc., have contributed to the increased attention to the resilience of the electric grid and ways to strengthen it.
