Derisking of subsynchronous torsional oscillations in power systems with conventional and inverter-based generation
Nicolas Bonafé, Julian Freytes, Hani Saad
This article proposes an application of a derisking methodology of subsynchronous torsional oscillations considering a realistic use case. The main objective is to summarize and dr…
Grid-Forming Control Based On Emulated Synchronous Condenser Strategy Compliant With Challenging Grid Code Requirements
Julian Freytes, Antoine Rossé, Valentin Costan +1
Future power systems will include high shares of inverter-based generation. There is a general consensus that for allowing this transition, the Grid-Forming (GFM) control approach…
Generalized Voltage-based State-Space Modelling of Modular Multilevel Converters with Constant Equilibrium in Steady-State
Gilbert Bergna-Diaz, Julian Freytes, Xavier Guillaud +2
This paper demonstrates that the sum and difference of the upper and lower arm voltages are suitable variables for deriving a generalized state-space model of an MMC which settles…
