Hidden Economic Consequences of Adapting to Fast Ramping Datacenter Loads
Willa Gutowski, Charles Foltz, Nicholson Koukpaizan +2
Artificial intelligence workloads are driving the rapid expansion of datacenter infrastructure, which imposes substantial stress on the US energy system. While high peak electricit…
Geospatial sensitivity of transmission-constrained ACOPF to generator retirement
Willa Gutowski, Ulyana Shyrokaya, Nicholson Koukpaizan +3
The US faces a growing resource adequacy challenge: new loads are being added at unprecedented scale while aging generating assets are being retired. In transmission-constrained gr…
HPC-Enabled Generator Importance Assessment for RTO-Scale Resource Adequacy Planning
Eve Tsybina, Nicholson Koukpaizan, Joshua Hambrick +2
Modern power systems are increasingly under stress as aging assets approach retirement and load growth outpaces new generation construction. The severity of this challenge varies b…
Scaling the memory wall using mixed-precision -- HPG-MxP on an exascale machine
Aditya Kashi, Nicholson Koukpaizan, Hao Lu +3
Mixed-precision algorithms have been proposed as a way for scientific computing to benefit from some of the gains seen for artificial intelligence (AI) on recent high performance c…
