California Test System (CATS): A Geographically Accurate Test System based on the California Grid
Sofia Taylor, Aditya Rangarajan, Noah Rhodes +3
This paper presents the California Test System (CATS), a synthetic transmission grid in California that can be used by the public for power systems policy research without revealin…
Chance-Constrained AC Optimal Power Flow for Unbalanced Distribution Grids
Kshitij Girigoudar, Ashley M. Hou, Line A. Roald
The growing penetration of distributed energy resources (DERs) is leading to continually changing operating conditions, which need to be managed efficiently by distribution grid op…
Enabling Undergrounding of Long-Distance Transmission Lines with Low Frequency AC Technology
David K. Sehloff, Line A. Roald
With increasing prevalence of severe natural hazards and the ignition of wildfires by power lines, many power system planners are considering converting overhead lines to undergrou…
Efficient Representations of Radiality Constraints in Optimization of Islanding and De-Energization in Distribution Grids
Joe Gorka, Line Roald
Optimization of power distribution system topology is complicated by the requirement that the system be operated in a radial configuration. In this paper, we discuss existing metho…
Recursive Restoration Refinement: A Fast Heuristic for Near-Optimal Restoration Prioritization in Power Systems
Noah Rhodes, Carleton Coffrin, Line Roald
The prioritization of restoration actions after large power system outages plays a key role in how quickly power can be restored. It has been shown that fast and intuitive heuristi…
Exploring the Impacts of Power Grid Signals on Data Center Operations using a Receding-Horizon Scheduling Model
Weiqi Zhang, Line A. Roald, Victor M. Zavala
Data centers (DCs) can help decarbonize the power grid by helping absorb renewable power (e.g., wind and solar) due to their ability to shift power loads across space and time. How…
Co-optimization of power line shutoff and restoration under high wildfire ignition risk
Noah Rhodes, Line Roald
Electric power infrastructure has ignited several of the most destructive wildfires in recent history. Preemptive power shutoffs are an effective tool to mitigate the risk of ignit…
Using Geographic Load Shifting to Reduce Carbon Emissions
Julia Lindberg, Bernard C. Lesieutre, Line A. Roald
An increasing focus on the electricity use and carbon emissions associated with computing has lead to pledges by major cloud computing companies to lower their carbon footprint. Da…
