Grid-forming control of three-phase and single-phase converters across unbalanced transmission and distribution systems
Shahin S. Nudehi, Dominic Groß
In this work, we investigate grid-forming control for power systems containing three-phase and single-phase converters connected to unbalanced distribution and transmission network…
Frequency Stability of Synchronous Machines and Grid-Forming Power Converters
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,…
Beyond low-inertia systems: Massive integration of grid-forming power converters in transmission grids
Alessandro Crivellaro, Ali Tayyebi, Catalin Gavriluta +4
As renewable sources increasingly replace existing conventional generation, the dynamics of the grid drastically changes, posing new challenges for transmission system operations,…
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…
