Quantifying the resilience benefits of undergrounding a circuit with utility data
Arslan Ahmad, Ian Dobson, Anne Kimber
We leverage historical outage data to quantify the resilience benefits of undergrounding a circuit. The historical performance of the overhead circuit is compared to the performanc…
Typical models of the distribution system restoration process
Arslan Ahmad, Ian Dobson
Accurate probabilistic modeling of the power system restoration process is essential for resilience planning, operational decision-making, and realistic simulation of resilience ev…
Measuring outage resilience in a distribution system with the number of outages in large events
Arslan Ahmad, Ian Dobson
We develop LENORI, a Large Event Number of Outages Resilience Index measuring distribution system resilience with the number of forced line outages observed in large extreme events…
Quantifying resilience for distribution system customers with SALEDI
Arslan Ahmad, Ian Dobson
The impact of routine smaller outages on distribution system customers in terms of customer minutes interrupted can be tracked using conventional reliability indices. However, the…
Quantifying Power Systems Resilience Using Statistical Analysis and Bayesian Learning
Apsara Adhikari, Charlotte Wertz, Anamika Dubey +2
The increasing frequency and intensity of extreme weather events is significantly affecting the power grid, causing large-scale outages and impacting power system resilience. Yet l…
Extracting resilience events from utility outage data based on overlapping times and locations
Arslan Ahmad, Ian Dobson
To study power system resilience with real data, it is necessary to group individual power outages recorded by utilities into events in which outages cluster and overlap due to ext…
Logarithmic resilience risk metrics that address the huge variations in blackout cost
Arslan Ahmad, Ian Dobson
Resilience risk metrics must address the customer cost of the largest blackouts of greatest impact. However, there are huge variations in blackout cost in observed distribution uti…
Resiliency metrics quantifying emergency response in a distribution system
Shikhar Pandey, Gowtham Kandaperumal, Arslan Ahmad +1
The electric distribution system is a cornerstone of modern life, playing a critical role in the daily activities and well-being of individuals. As the world transitions toward a d…
The improvement in transmission resilience metrics from reduced outages or faster restoration can be calculated by rerunning historical outage data
Arslan Ahmad, Ian Dobson, Svetlana Ekisheva +2
Transmission utilities routinely collect detailed outage data, including resilience events in which outages bunch up due to weather. The resilience events and their resilience metr…
Quantifying distribution system resilience from utility data: large event risk and benefits of investments
Arslan Ahmad, Ian Dobson
We focus on large blackouts in electric distribution systems caused by extreme winds. Such events have a large cost and impact on customers. To quantify resilience to these events,…
