Resilience Framework for Electric Energy Delivery Systems (R.1)

Abstract

T he intent of this document is to introduce a framework that will enable more thoughtful and deliberate consideration of resilience as it relates to electrical energy delivery systems (EEDS), with specific application to distributed wind systems. The need for this framework was established in a previous report from Idaho National Laboratory (INL), Distributed Wind Resilience Metrics for Electric Energy Delivery Systems, where definitions of resilience and resilience of EEDS were developed and a critical characteristic of resilience for EEDS, the distinctiveness quality, was identified. 1 This distinctiveness quality reflects the difficulty in applying resilience metrics broadly to the widely varied risk perception of stakeholders and stakeholder groups, the varied range of potential consequences to a system based upon events, and the large set of potential mitigation strategies. Development of resilience metrics, and more specifically distributed wind resilience metrics, must come from a resilience process that addresses this distinctiveness quality and is separate from well-established reliability processes. These two factors are the primary drivers demonstrating the need to establish a resilience methodology that can be applied to any electrical energy delivery system, any set of stakeholders, and any set of events.This framework is proposed under the Department of Energy (DOE) Wind Energy Technologies Office (WETO) Microgrids, Infrastructure Resilience, and Advanced Controls Launchpad (MIRACL) project. While the focus of this project is on distributed wind, INL believes resilience is best evaluated at a system level. As such, the framework has been developed to broadly apply to EEDS so that all elements of systems that contain distributed wind can be part of the resilience evaluation. With this broad view, it is also possible to apply this framework to systems without distributed wind.

“…The INL resilience framework is a flexible set of guidelines that enables users to define, evaluate, and improve resilience for electrical energy delivery systems (EEDS), with a specific application to distributed wind systems (Culler et al 2021). Although the concept of resiliency is not new, its application to the electric grid is neither standardized nor well-defined, and there is little to no guidance on how to evaluate resilience specifically for distributed wind systems.…”

“…Others emphasize methods to plan and prepare for resilience [10]- [12]. The resilience framework developed by INL uniquely covers the entire system lifecyle, and it evaluates resilience using specific steps [6]. As such, it is the chosen framework to employ in this case study.…”

“…To address the need for resilience planning in the power industry, Idaho National Laboratory (INL) has developed a resilience framework for EEDS [6]. This framework is intended to help identify, assess, and mitigate risks associated with resilience hazards.…”

“…A three-tiered approach is developed in the resilience framework [3]. At the top level, three stages of resilience represent different times in a system's lifecycle and different means of evaluating and executing resilience.…”
