Power systems are among the most hazard-sensitive and interdependent lifelines.
Extreme wind, flooding, and storm surge can trigger component failures and cascading outages.
DM2L develops mechanics-to-network resilience frameworks for transmission and distribution systems,
supporting outage prediction, hardening strategies, and restoration planning.

Core Research Focus

• Fragility and vulnerability modeling of transmission and distribution assets
• Wind-induced structural demand and failure of towers and poles
• Flood and surge vulnerability of substations and critical nodes
• Outage prediction under spatially heterogeneous hazards
• Hardening strategy evaluation and restoration optimization

What Has Been Done

• Developed physics-based fragility models for power system components under extreme winds
• Integrated hazard exposure with component failure probability and network disruption
• Advanced frameworks linking structural vulnerability to system-level outage risk

What We Are Doing Now

• Hybrid physics–AI outage prediction and uncertainty-aware reliability assessment
• Multi-hazard risk mapping for grid assets and scenario-based disruption modeling
• Coupling grid disruption with transportation access and restoration constraints

Strategic Plan

1. Develop a probabilistic fragility library for grid assets under compound hazards
2. Build scalable digital-twin-ready models linking damage → functionality → recovery
3. Optimize hardening and restoration strategies under budget, logistics, and equity constraints
4. Support decision workflows for utilities and agencies under future climate and hazard regimes

How This Connects

This thrust anchors DM2L’s lifeline resilience research and links directly to infrastructure interdependency,
cascading risk, and community resilience metrics, enabling system-of-systems resilience assessment.
