Adapting Existing Energy Planning, Simulation, and Operational Models for Resilience Analysis

Vulnerability and resilience of power systems infrastructure to natural hazards and climate change

“…Measuring resilience is critically important to identifying interventions and processes that can create a more resilient system (Hallegatte & Engle, 2019). However, resilience metrics in infrastructure analysis are more nascent than similar indicators in vulnerability or risk management practice and suffer from similarly‐wide disagreement between stakeholders as defining the term itself (Murphy et al, 2020). While this may allow for broader application in policy‐making, it hinders the operationalization of resilient investments.…”

“…A note here is that this definition aligns with aspects of “reliability” in the power sector. Reliability, however, generally refers to similar considerations (power delivery to the end user) but is focused on operability considerations in normal circumstances and generally applies to small, more frequent disruptions, both geographically and temporally (Anderson et al, 2020; Murphy et al, 2020; Mathaios Panteli & Mancarella, 2015b). Resilience focuses on larger, more rare events that have broader systemic implications (Murphy et al, 2020).…”

“…The use of available tools to identify ways to quantify, compare, and visualize these risks can provide some insights. Murphy et al (2020) investigated the application of five existing power system planning tools to identify metrics that can inform resilience, including economic factors, unserved energy assessments, and social impacts from power loss. The use of geospatial systems such as ArcGIS, QGIS and others also provides a framework for evaluating data in a location‐specific way.…”

“…Measuring resilience through defined metrics is an emerging field of research. In many cases, power system operability metrics are being defined by, and in contrast with, existing metrics for reliability (Murphy et al, 2020; Mathaios Panteli & Mancarella, 2015b). The value of lost load (VOLL) metric is commonly used by utilities and agencies to measure the cost of outages but is often represented as a static cost.…”

“…It also highlights the importance of considering resilience from a systemic perspective, ensuring that context‐specific information is being considered such as the resilience of whom, what, and for what purpose? A noted issue with metrics is the limited availability of data, from basic direct inputs such as the time‐dependent VOLL to different customers to more indirect, but perhaps more valuable, issues of indirect impacts to other critical infrastructure (health, water, transportation) and the resulting consequences to health, safety and welfare during a hazard event (Anderson et al, 2020; Hallegatte et al, 2019; Murphy et al, 2020).…”
