Probabilistic Quantification of Distribution System Resilience for an Extreme Event
Table 1
Limitation in current metrics and/or quantifications of power system resilience.
Limitation 1. Impacts of upcoming extreme weather events
1. Does not give any insight into the probable effects of an upcoming extreme event.
2. Does not accurately assess the effects of extreme events on network performance loss and the expected energy not provided during the event.
3. The resilience characteristics of the network change as the event progresses. The network’s resilience equates to distinct network features for every stage of an event. Not including these features based on the advancement of events leads to an under-appreciated resilience assessment that may result in network failure.
Limitation 2. Dimensions of critical resilience
1. The impact of operational actions aided by smart technology on a network’s resilience during extreme events has not been thoroughly examined.
2. Do not consider how quickly resilience degrades when an electric network is affected by an event or how lengthy the network remains in after event degradation phases before the recovery process begins and when it has been restored.
3. Be unable to provide a complete view of a network’s resilience at all stages of an event.
