Roald Line

Roald Line is an Associate Professor in the Department of Electrical and Computer Engineering at the University of Wisconsin–Madison. He holds affiliations with the Nelson Institute for Environmental Studies and the Center for Climatic Research. His research focuses on optimizing power systems for resilience, decarbonization, and wildfire risk mitigation. He develops advanced mathematical frameworks and machine learning models to address challenges in grid operations under uncertainty.

Key research areas include stochastic optimization for power systems, renewable energy integration, carbon-aware grid management, and geospatial wildfire risk modeling. He has pioneered frameworks for carbon intensity analysis (e.g., Electricityemissions.jl), grid topology optimization, and real-time security assessment systems. His work bridges theoretical advancements with practical implementations in smart grids and energy markets.

Recent contributions emphasize wildfire risk mitigation through optimal power shutoff strategies, hydrogen electrolyzer scheduling, and resilient microgrid design. His publications frequently appear in top energy systems journals and conferences, demonstrating impactful interdisciplinary work at the intersection of electrical engineering, environmental science, and operations research.
