INCREASING THE RESILIENCE
of critical power infrastructures
to high-impact, low-probability
events, such as extreme weather
phenomena driven by climate
change, is of key importance for
keeping the lights on. However,
what does resilience really mean?
Should we build a stronger and bigger grid or a smarter one? This article
discusses a conceptual framework of
power system resilience, its key features,
and potential enhancement measures.
Introduction
The design and operation of critical power
infrastructures around the world has been
traditionally driven by the key reliability
principles of security and adequacy. These
principles allow the infrastructure to deal with
known and credible threats so as to guarantee a
high-quality power supply to end users on a nearly continuous basis, with few interruptions over an extended
time period. It cannot be doubted that this has led to the
development of one of the most reliable (and complex!)
infrastructures of the last century.
However, it is becoming more and more apparent that
further considerations beyond the classical reliabilityoriented view are needed for keeping the lights on. This
The Grid:
Stronger, Bigger,
Smarter?
