Using historical utility outage data to compute overall transmission grid resilience

TLDR
This work quantifies resilience in electric power transmission networks in a new and comprehensive way that can represent the multiple processes of resilience.
Abstract
Given increasing risk from climate-induced natural hazards, there is growing interest in the development of methods that can quantitatively measure resilience in power systems. This work quantifies resilience in electric power transmission networks in a new and comprehensive way that can represent the multiple processes of resilience. A novel aspect of this approach is the use of empirical data to develop the probability distributions that drive the computational model. This paper demonstrates the approach by measuring the impact of one potential improvement to a power system. Specifically, we measure the impact of additional distributed generation (DG) on power system resilience, and find that DG can substantially increase resilience.

Identifying Optimal Portfolios of Resilient Network Investments Against Natural Hazards, With Applications to Earthquakes

TL;DR: This work proposes a practical framework that can be used to identify network investments that offer the highest level of hedge against risks caused by natural hazards and uses a simulation to evaluate the resilience level improvements associated with the network investment propositions.

A Risk-Based Approach to Assess the Operational Resilience of Transmission Grids

TL;DR: A risk-based assessment using North American Electric Reliability Corporation (NERC) Transmission Availability Data System (TADS) for the North American bulk power system (BPS) finds that the quantification of nearby unscheduled outage clusters would improve the response times for operators to readjust the system and provide better resilience still under the standard definition of N-1 security.

Can the Markovian influence graph simulate cascading resilience from historical outage data

TL;DR: This work proposes using a Markovian influence graph driven by historical utility data to sample the cascades and contributes a high-level simulation of cascading line outages that is driven by standard utility data.

Power-Law Distributions in Empirical Data

TL;DR: This work proposes a principled statistical framework for discerning and quantifying power-law behavior in empirical data by combining maximum-likelihood fitting methods with goodness-of-fit tests based on the Kolmogorov-Smirnov (KS) statistic and likelihood ratios.

Resilience, Adaptability and Transformability in Social–ecological Systems

TL;DR: The concept of resilience has evolved considerably since Holling's (1973) seminal paper as discussed by the authors and different interpretations of what is meant by resilience, however, cause confusion, and it can be counterproductive to seek definitions that are too narrow.

Metrics and Quantification of Operational and Infrastructure Resilience in Power Systems

TL;DR: In this article, the resilience trapezoid is defined and quantified using time-dependent resilience metrics that are specifically introduced to help capture the critical system degradation and recovery features associated to the trapezoids for different temporal phases of an event.
