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…
Physics-Informed Neural Network Models for EMT Simulators
Ignasi Ventura Nadal, Mohammad Kazem Bakhshizadeh, Petros Aristidou +4
This is the first paper, to the best of our knowledge, to propose a framework that integrates Physics-Informed Neural Network (PINN) models in Electromagnetic Transient (EMT) simul…
Methodologies for offshore wind power plants stability analysis
Germano R. Mugambi, Nicolae Darii, Hesam Khazraj +4
The development of larger Offshore Wind Power Plants (OWPPs) is moving towards multi-vendor setups, ultimately aiming to establish Energy hubs. These structures are characterized b…
