Strengthening AC optimal power flow relaxation through offline bound tightening and linear approximations
Xiangxin An, Constance Crozier, Santanu S. Dey
The alternating-current optimal power flow (ACOPF) problem is fundamental to power system operation and planning, but its nonconvexity makes globally optimal solutions of large-sca…
CRUX: A topology-aware load balancer for mesh-based fluid dynamics codes on GPU clusters
M. T. P. Liska, C. Crozier
The rapid growth of computational power has revolutionized numerical simulations, profoundly enhancing our understanding of fluids and plasmas. Computational fluid dynamics (CFD) s…
Quantifying and Attributing Power Flexibility from GPU-Heavy Data Centers
Yiru Ji, Constance Crozier, Matthew Liska
The growth of GPU-heavy data centers has increased electricity demand and challenged grid stability. This paper investigates how an energy-aware job scheduling algorithm provides f…
On the Potential of Electrified Supply Chains to Provide Long Duration Demand Flexibility
Rina Davila Severiano, Constance Crozier, Mark O Malley
Demand flexibility can offset some of the variability introduced on the supply-side by variable renewable generation. However, most efforts (e.g. control of residential vehicle cha…
