To cope with a potential increase in the frequency and severity of
natural disasters, proactive operational and planning measures are
expected to ensure an uninterrupted power supply.
rooms, the path toward achieving network-level optimiza-
tion is also continuously evolving. Just like the adoption of
many new technologies, once the technical foundations have
been established, other opportunities that further exploit the
technology also arise. Some of these emerging concepts are
further explored later in this article.
Model-Based Resilient Distribution
System Restoration
Extreme weather events have a significant impact on the
aging power distribution infrastructure. These high-impact,
low probability (HILP) events often result in extended out-
ages and the loss of critical services, which may severely
affect customer safety. This results in the critical need to
improve distribution system resilience for natural disasters.
Grid resilience is characterized by the ability to withstand
and recover from HILP events. One of the requirements for
a resilient distribution system is the ability to restore power
to critical loads for the duration of the outage. During a natu-
ral disaster, when the main power grid supplying distribution
system is unavailable, traditional distribution system restora-
tion (DSR) approaches are inapplicable, calling for advanced
system restoration methods. One such approach is to utilize
DERs as community resources by extending their zone of
service to other loads.
Traditionally, distribution companies employ an FLISR
system for DSR during outages. Current industry prac-
tices for service restoration are largely manual, based on
a centralized decision-support system located at the util-
ity control center, and do not actively utilize all available
