A Resilience Toolbox and Research Design for Black Sky Hazards to Power Grids

Abstract EN

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.
