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(More)
The modular multilevel converter (MMC) topology is characterized by excellent scalability. Converters with direct connection to high voltages in the range of several 100 kV can be built by stacking comparatively simple modules. The drawback of the technology is the single-phase structure, causing, among others, oscillations of the capacitor voltages which(More)
