Acceleration of Power System Dynamic Simulations using a Deep Equilibrium Layer and Neural ODE Surrogate

no code implementations10 May 2024 Matthew Bossart, Jose Daniel Lara, Ciaran Roberts, Rodrigo Henriquez-Auba, Duncan Callaway, Bri-Mathias Hodge

The dominant paradigm for power system dynamic simulation is to build system-level simulations by combining physics-based models of individual components.

Small-signal stability in inverter-dominated grids: exploring the role of gains, line dynamics, and operating conditions

1 code implementation20 Nov 2023 Ruth Kravis, Gabriel Colon-Reyes, Duncan Callaway

In this work we study the small-signal stability characteristics of a power system comprised of inverter and synchronous machine sources, and consider the effect of inverter control gains, transmission line dynamics, and network operating conditions.

Transmission line dynamics on inverter-dominated grids: analysis and simulations

no code implementations12 Oct 2023 Gabriel E. Colon-Reyes, Ruth Kravis, Sunash Sharma, Duncan Callaway

We utilize an open-source modeling platform to perform both small signal stability and dynamic time domain studies of networks containing inverters, machines, and loads.

Towards Distributed Energy Services: Decentralizing Optimal Power Flow with Machine Learning

no code implementations14 Jun 2018 Roel Dobbe, Oscar Sondermeijer, David Fridovich-Keil, Daniel Arnold, Duncan Callaway, Claire Tomlin

We consider distribution systems with multiple controllable Distributed Energy Resources (DERs) and present a data-driven approach to learn control policies for each DER to reconstruct and mimic the solution to a centralized OPF problem from solely locally available information.
