Abstract

A structured collection of tools for engineering resilience and a research approach to improve the resilience of a power grid are described in this paper. The collection is organized by a two-dimensional array formed from typologies of power grid components and business processes. These two dimensions provide physical and operational outlooks, respectively, for a power grid. The approach for resilience research is based on building a simulation model of a power grid which utilizes a resilience assessment equation to assess baseline resilience to a hazards’ profile, then iteratively selects a subset of tools from the collection, and introduces these as interventions in the power grid simulation model. Calculating the difference in resilience associated with each subset supports multicriteria decision-making to find the most convenient subset of interventions for a power grid and hazards’ profile. Resilience is an emergent quality of a power grid system, and therefore resilience research and interventions must be system-driven. This paper outlines further research required prior to the practical application of this approach.

Summary

Introduction

Power grids play an important role for modern society [1]. A failure in a power grid demonstrates a lack of engineered and engineering resilience to one or more hazards. A failure in a power grid may result in follow-up failures in the grid and other infrastructures [2]. Bo et al [3] mapped and summarized 23 major blackouts from 1965 to 2012, representing major failures in power grids. No additional major blackouts were found, which is partially validated by the list of billion-dollar weather and climate disasters [4] in the US. Statistical studies show that major outages happen more often than can be concluded from statistics on minor and intermediate outages [5, 6]
