Frequency shaping control for weakly-coupled grid-forming IBRs
Bala Kameshwar Poolla, Yashen Lin, Andrey Bernstein +2
We consider the problem of controlling the frequency of low-inertia power systems via inverter-based resources (IBRs) that are weakly connected to the grid. We propose a novel grid…
Power-balancing dual-port grid-forming power converter control for renewable integration and hybrid AC/DC power systems
Irina Subotić, Dominic Groß
In this work, we investigate grid-forming (GFM) control for dc/ac power converters in emerging power systems that contain ac and dc networks, renewable generation, and conventional…
A Lyapunov framework for nested dynamical systems on multiple time scales with application to converter-based power systems
Irina Subotić, Dominic Groß, Marcello Colombino +1
In this work, we present a Lyapunov framework for establishing stability with respect to a compact set for a nested interconnection of nonlinear dynamical systems ordered from slow…
Interactions of Grid-Forming Power Converters and Synchronous Machines
Ali Tayyebi, Dominic Groß, Adolfo Anta +2
An inevitable consequence of the global power system transition towards nearly 100% renewable-based generation is the loss of conventional bulk generation by synchronous machines,…
Dispatchable Virtual Oscillator Control for Decentralized Inverter-dominated Power Systems: Analysis and Experiments
Gab-Su Seo, Marcello Colombino, Irina Subotić +3
This paper presents an analysis and experimental validation of dispatchable virtual oscillator control (dVOC) for inverter-dominated power systems. dVOC is a promising decentralize…
Placement and Implementation of Grid-Forming and Grid-Following Virtual Inertia and Fast Frequency Response
Bala Kameshwar Poolla, Dominic Groß, Florian Dörfler
The electric power system is witnessing a shift in the technology of generation. Conventional thermal generation based on synchronous machines is gradually being replaced by power…
The effect of transmission-line dynamics on grid-forming dispatchable virtual oscillator control
Dominic Groß, Marcello Colombino, Jean-Sébastien Brouillon +1
In this work, we analyze the effect of transmission line dynamics on grid-forming control for inverter-based AC power systems. In particular, we investigate a dispatchable virtual…
Global phase and magnitude synchronization of coupled oscillators with application to the control of grid-forming power inverters
Marcello Colombino, Dominic Groß, Jean-Sébastien Brouillon +1
In this work, we explore a new approach to synchronization of coupled oscillators. In contrast to the celebrated Kuramoto model we do not work in polar coordinates and do not consi…
On the steady-state behavior of a nonlinear power system model
Dominic Groß, Catalin Arghir, Florian Dörfler
In this article, we consider a dynamic model of a three-phase power system including nonlinear generator dynamics, transmission line dynamics, and static nonlinear loads. We define…
