Resumen
Even though the concept of resilience is becoming
widely used in electric power systems, there is no consensus on
how to systematically model or quantify it. This article begins by
proposing a classification for different types of system risk
analyses, associating them to the concept of power systems
resilience. Thereafter, it describes and applies a resilience
assessment and adaptation framework to the Northern Chilean
electric power system in the context of its exposure to seismic
events. This time-dependent analysis is evaluated throughout the
disaster’s impact and the network’s operation and restoration
timeframes with two indices: Energy not Supplied and Energy
Index of Unreliability. Finally, the article compares a base case
with three resilience adaptation strategies, namely, robust,
redundant and responsive cases, in terms of their expected
energy annual loss and the return period of different levels of
network performance.
