VIAvento — A fast and accurate simulation tool for power-electronic systems

Simulating complex offshore grids including connected devices and independent control algorithms (e.g. in DLL form) is essential for the assessment of global system stability. In power-electronic applications - due to independently controlled and independently switching inverters - only time domain simulation can give meaningful results. This paper presents the simulation tool VIAvento which satisfies the introduced requirements. The functioning of this tool is illustrated by showing simulation results of connected two-point converters and one HVDC in modular-multilevel-converter topology (MMC topology).
