EMT and RMS Modeling of Thyristor Rectifiers for Stability Analysis of Converter-Based Systems
Ognjen Stanojev, Pol Jane Soneira, Gösta Stomberg +1
Thyristor rectifiers are a well-established and cost-effective solution for controlled high-power rectification, commonly used for hydrogen electrolysis and HVDC transmission. Howe…
The role of VSG parameters in shaping small-signal SG dynamics
Ferdinand Geuss, Orcun Karaca, Mario Schweizer +1
We derive a small-signal transfer function for a system comprising a virtual synchronous generator (VSG), a synchronous generator (SG), and a load, capturing voltage and frequency…
Grid-Forming Vector Current Control FRT Modes Under Symmetrical and Asymmetrical Faults
Ognjen Stanojev, Orcun Karaca, Mario Schweizer
Recent research has shown that operating grid-connected converters using the grid-forming vector current control (GFVCC) scheme offers significant benefits, including the simplicit…
Robust black start of an offshore wind farm with DRU based HVDC link using power synchronization control
Orcun Karaca, Ioannis Tsoumas, Mario Schweizer +2
This paper introduces a universal power synchronization controller for grid-side control of the wind turbine conversion systems in an offshore wind farm with a diode rectifier in t…
