Nodal Frequency Stability-Constrained UC & ED for Renewable-Dominated Power Systems
Marena Trujillo, David Cole, Bri-Mathias Hodge
In modern power systems with high shares of renewable, inverter-based resources (IBRs), frequency stability becomes more complex due to the fast dynamics of IBRs and frequency traj…
Implications of Grid-Forming Inverter Parameters on Disturbance Localization and Controllability
Matt Baughman, Marena Trujillo, Bri-Mathias Hodge +1
The shift from traditional synchronous generator (SG) based power generation to generation driven by power electronic devices introduces new dynamic phenomena and considerations fo…
Analytical Models of Frequency and Voltage in Large-Scale All-Inverter Power Systems
Marena Trujillo, Amir Sajadi, Bri-Mathias Hodge
Low-order frequency response models for power systems have a decades-long history in optimization and control problems such as unit commitment, economic dispatch, and wide-area con…
Computationally Efficient Analytical Models of Frequency and Voltage in Low-Inertia Systems
Marena Trujillo, Amir Sajadi, Jonathan Shaw +1
In this paper, low-order models of the frequency and voltage response of mixed-generation, low-inertia systems are presented. These models are unique in their ability to efficientl…
