PowerSimulationsDynamics.jl -- An Open Source Modeling Package for Modern Power Systems with Inverter-Based Resources

1 code implementation5 Aug 2023 Jose Daniel Lara, Rodrigo Henriquez-Auba, Matthew Bossart, Duncan S. Callaway, Clayton Barrows

In this paper we present the development of an open-source simulation toolbox, PowerSimulationsDynamics. jl, to study the dynamic response of power systems, focusing on the requirements to model systems with high penetrations of Inverter-Based Resources (IBRs).

Revisiting Power Systems Time-domain Simulation Methods and Models

1 code implementation24 Jan 2023 Jose Daniel Lara, Rodrigo Henriquez-Auba, Deepak Ramasubramanian, Sairaj Dhople, Duncan S. Callaway, Seth Sanders

The changing nature of power systems dynamics is challenging present practices related to modeling and study of system-level dynamic behavior.

Small-Signal Stability Impacts of Load and Network Dynamics on Grid-Forming Inverters

no code implementations15 Dec 2022 Rodrigo Henriquez-Auba, Jose Daniel Lara, Duncan S. Callaway

In this paper, we perform eigenvalue analyses for inverter-based resources and synchronous machines connected to a load and explore the effects of multiples models under different network representations.

Predicting Electricity Infrastructure Induced Wildfire Risk in California

no code implementations6 Jun 2022 Mengqi Yao, Meghana Bharadwaj, Zheng Zhang, Baihong Jin, Duncan S. Callaway

Our data include historical ignition and wire-down points triggered by grid infrastructure collected between 2015 to 2019 in Pacific Gas & Electricity territory along with various weather, vegetation, and very high resolution data on grid infrastructure including location, age, materials.

Online Convex Optimization with Binary Constraints

no code implementations5 May 2020 Antoine Lesage-Landry, Joshua A. Taylor, Duncan S. Callaway

Then, we derive a finite-time bound that is sublinear in time and linear in the cumulative variation of the relaxed, continuous round optima.

LITS.jl -- An Open-Source Julia based Simulation Toolbox for Low-Inertia Power Systems

1 code implementation5 Mar 2020 Rodrigo Henriquez-Auba, Jose D. Lara, Ciaran Roberts, Nathan Pallo, Duncan S. Callaway

Case studies are selected to showcase the integration of different device models' behavior in power systems.

Dynamic and Distributed Online Convex Optimization for Demand Response of Commercial Buildings

no code implementations31 Jan 2020 Antoine Lesage-Landry, Duncan S. Callaway

We extend the regret analysis of the online distributed weighted dual averaging (DWDA) algorithm [1] to the dynamic setting and provide the tightest dynamic regret bound known to date with respect to the time horizon for a distributed online convex optimization (OCO) algorithm.
