Fast Frequency Services from HVDC-Connected Offshore Wind Power Plants: A Review in the European Context
Zhenghua Xu, George Alin Raducu, Behnam Nouri +2
The rapid expansion of offshore wind energy is central to the European Union's climate-neutrality targets, with High Voltage Direct Current-connected offshore wind power plants (HV…
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…
Small-Signal Analyses Using Analytical IBR Models and Frequency-Dependent Thévenin Equivalents
Nicolae Darii, Alberto Magagna, Oscar Saborio-Romano +1
This paper investigates whether component-level studies can capture additional interactions through Small Signal Analysis (SSA) when the network connected to the Voltage Source Con…
Enhancing Offshore Wind Simulations: Interpolated Switching via DLL Black-Boxes
Nicolae Darii, Ranjan Sharma, Vladislav Akhmatov +4
The modern power system, increasingly composed of Inverter-Based Resources (IBR) from multiple manufacturers, requires new study and design techniques that balance accuracy with th…
Systematic Gray-Box Identification Methodology for Voltage Source Converters
Nicolae Darii, Luis A. Garcia-Reyes, Ignasi Ventura Nadal +4
This paper introduces a systematic gray-box identification framework for voltage-source converter models based solely on terminal time-series data. The proposed approach combines a…
Estimation of Equivalent SCR for Offshore Wind
Nicolae Darii, Ranjan Sharma, Germano Rugendo Mugambi +2
The integration of offshore wind power plants (OW-PPs) into weak grids can pose stability challenges due to the interaction between inverter-based resources (IBRs), Flexible AC Tra…
