摘要：Thanks to scalability, performance and efficiency, the Modular Multilevel Converter (MMC),
since its invention, becomes an attractive topology in industrial applications such as high
voltage direct current (HVDC) transmission system. However, modelling challenges related to
the high number of switching elements in the MMC are highlighted when such systems are
integrated into large simulated networks for stability or protection algorithms testing. In this
work, a novel dynamic models for MMC is proposed. The proposed models are intended to
simplify modeling challenges related to the high number of switching elements in the MMC. The
models can be easily used to simulate the converter for stability analysis or protection
algorithms for HVDC grids.
