A Dynamic Phasor Framework for Analysis of Subsynchronous Oscillations in Multi-Machine Systems with IBRs and Large Loads
Fiaz Hossain, Nilanjan Ray Chaudhuri, Constantino M. Lagoa +3
Although the electromagnetic transient (EMT) framework can capture subsynchronous oscillations (SSOs), it faces scalability issues for large-scale systems. Thus motivated, we propo…
Limiting the Impact of AI Data Centers on Fatigue Life of Thermal Turbine Generators in the Grid: A Frequency-Domain Approach
Fiaz Hossain, Nilanjan Ray Chaudhuri, Alok Sinha +2
A framework is established that assesses the impact of variations in artificial intelligence (AI) data center (DC) loads on the fatigue damage of steam/gas turbines of the synchron…
A Dynamic Phasor Framework for Analysis of IBR-Induced SSOs in Multi-Machine Systems
Fiaz Hossain, Nilanjan Ray Chaudhuri, Constantino M. Lagoa
We propose a generalized dynamic phasor (DP) framework to analyze inverter-based resources (IBRs) connected to multi-machine systems under balanced and unbalanced conditions. It ca…
A Dynamic Phasor Framework for Analysis of Grid-Forming Converter Connected to Series-Compensated Line
Fiaz Hossain, Nilanjan Ray Chaudhuri
A dynamic phasor (DP) framework for time-domain and frequency-domain analyses of grid-forming converters (GFCs) connected to series-compensated transmission lines is proposed. The…
Robust Adaptive Supplementary Control for Damping Weak-Grid SSOs Involving IBRs
Sina Ameli, Lilan Karunaratne, Nilanjan Ray Chaudhuri +1
Subsynchronous oscillations (SSOs) involving grid-following converters (GFLCs) connected to weak grids are a relatively new phenomena observed in modern power systems. SSOs are fur…
