California Test System (CATS): A Geographically Accurate Test System based on the California Grid

1 code implementation9 Oct 2022 Sofia Taylor, Aditya Rangarajan, Noah Rhodes, Jonathan Snodgrass, Bernie Lesieutre, Line A. Roald

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 revealing any critical energy information.

Chance-Constrained AC Optimal Power Flow for Unbalanced Distribution Grids

no code implementations19 Jul 2022 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 operators.

Enabling Undergrounding of Long-Distance Transmission Lines with Low Frequency AC Technology

no code implementations17 Jun 2022 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 underground cables to mitigate risks related to these events.

Exploring the Impacts of Power Grid Signals on Data Center Operations using a Receding-Horizon Scheduling Model

no code implementations13 Apr 2022 Weiqi Zhang, Line A. Roald, Victor M. Zavala

An obstacle that arises here is the lack of computationally-tractable DC operation models that can capture objectives, constraints, and information flows that arise at the interface of DCs and the power grid.

A Framework for Risk Assessment and Optimal Line Upgrade Selection to Mitigate Wildfire Risk

1 code implementation14 Oct 2021 Sofia Taylor, Line A. Roald

As wildfires in the United States are becoming more frequent and severe, mitigating wildfire ignition risk from power line faults is an increasingly crucial effort.

Statistical Learning For DC Optimal Power Flow

1 code implementation23 Jan 2018 Yeesian Ng, Sidhant Misra, Line A. Roald, Scott Backhaus

Although the number of possible bases is exponential in the size of the system, we show that only a few of them are relevant to system operation.
