Modelling of Modular Multilevel Converters for Fast and Accurate Simulation of Electromagnetic Transient Phenomena in HVDC Applications

Modular multilevel converters (MMC) are gradually becoming the technology of choice in high-voltage direct current (HVDC) power transmission for grid integration of large-scale offshore wind farms and multi-terminal HVDC transmission schemes. Each phase of an MMC HVDC terminal consists of several hundreds of identical submodules that switch a...
