Universal dual-port grid-forming control: bridging the gap between grid-forming and grid-following control
Irina Subotić, and Dominic Groß
We analyze a dual-port grid-forming (GFM) control for power systems containing ac and dc transmission, converter-interfaced generation and energy storage, and legacy generation. To…
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 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…

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,…
