Analysis of Bifurcation Behaviors in MMC Connected to a Weak Grid
Haoxiang, Zong; Lyu, Jing; Xu, Cai; Molinas Cabrera, Maria Marta; Zhang, Chen; Renxing, Yang; Fangquan, Rao (Chapter, 2018)Conventional small-signal approaches present obvious advantages applied in analyzing closed-loop stability in power electronics systems. However, linearized models fall short of predicting any nonlinear behavior which means ... -
Harmonic State Space Modeling and Analysis of Modular Multilevel Converter
Jing, Lyu; Xu, Cai; Xing, Zhang; Molinas Cabrera, Maria Marta (Chapter, 2018)Modular multilevel converter (MMC) has complex internal dynamics, such as capacitor voltage fluctuations and harmonic circulating currents, which may have a big impact on the terminal behaviors of the MMC. Therefore, it ...
