Stability and convergence of multi-converter systems using projection-free power-limiting droop control
Amirhossein Iraniparast, Dominic GroÃ
In this paper, we propose a projection-free power-limiting droop control for grid-connected power electronics and an associated constrained flow problem. In contrast to projection-…
Transient Stability of Offshore Energy Hubs
Alban J. F. Duvivier, Dominic GroÃ, Daniel Müller +1
Offshore energy hubs (OEHs) use grid-forming modular multilevel converters (MMCs) to enable large-scale offshore wind integration and multi-terminal HVDC operation. In HVDC-connect…
Holistic Grid-Forming Control to Enhance the Frequency Support from HVDC-Connected Offshore Wind Power Plants
Zhenghua XU, Dominic GroÃ, George Alin Raducu +3
To address the frequency stability challenges posed by the rising penetration of power electronics in power systems, HVDC-connected offshore wind power plants (OWPPs) are increasin…
Input-Output Specifications and Dynamic Droop Coefficients: Stability and Performance Conditions for Grid-Forming IBRs
Jennifer T. Bui, Dominic GroÃ
This paper proposes dynamic stability and performance conditions for grid-connected inverter-based resources (IBRs). To this end, we extend the notion of steady-state droop coeffic…
Improving Stability Margins with Grid-Forming Damper Winding Emulation
Dahlia Saba, Dominic GroÃ
This work presents (i) a framework for certifying small-signal frequency stability of a power system with line dynamics and heterogeneous bus dynamics, (ii) a novel reduced-order m…
Constraint-Aware Grid-Forming Control for Current Limiting
Dominic GroÃ
This work develops a constraint-aware grid-forming (GFM) control that explicitly accounts for current limits and modulation limits within the GFM oscillator dynamics generating the…
