Grid-forming control for power converters based on matching of synchronous machines
TL;DR: In this paper, the authors consider the problem of grid-forming control of power converters in low-inertia power systems and propose a novel converter control strategy which dwells upon the main characteristic of a synchronous machine (SM) model, the presence of an internal rotating magnetic field.

Grid-forming Control for Power Converters based on Matching of Synchronous Machines
TL;DR: A novel grid-forming converter control strategy which dwells upon the main characteristic of a SM: the presence of an internal rotating magnetic field is proposed, and a virtual oscillator is augmented whose frequency is driven by the DC-side voltage measurement and which sets the converter pulse-width-modulation signal.
Journal ArticleDOI
Grid-Friendly Matching of Synchronous Machines by Tapping into the DC Storage*
TL;DR: In this paper, the authors proposed a modulation control strategy for grid-forming converters in low-inertia power grids, inspired by identifying the structural similarities between the 3-phase DC/AC converter and the synchronous machine model.
Journal ArticleDOI
The Electronic Realization of Synchronous Machines: Model Matching, Angle Tracking, and Energy Shaping Techniques
Catalin Arghir,Florian Dörfler +1 more
TL;DR: This article investigates grid-forming and grid-following control strategies starting from a nonlinear state-space modeling viewpoint and shows how a minimal augmentation of the dc-link capacitance constitutes an exact physical realization without requiring inner-current loops.
Journal ArticleDOI
On the steady-state behavior of a nonlinear power system model
TL;DR: A dynamic model of a three-phase power system including nonlinear generator dynamics, transmission line dynamics, and static nonlinear loads is considered, which allows to recover the steady-state of the entire power system solely from a prescribed operating point of the transmission network.
