With the substantive increase in the proportion of voltage-source converter (VSC)-based
equipment, traditional power systems that primarily constituted of synchronous generators …

The modular multilevel converter (MMC) is currently one of the power converter topologies
which has attracted more research and development worldwide. Its features, such as high …

Inverter-based resources (IBRs) possess dynamics that are significantly different from those
of synchronous-generator-based sources and as IBR penetrations grow the dynamics of …

The offshore ac side impedance model of the modular multilevel converter (MMC) based
high voltage direct current (HVdc) system is essential for analyzing the interaction stability …

建模方法, 并应用于模块化多电平换流器(MMC) 空母线高频谐振问题的分析 …

Impedance modeling of a permanent magnet synchronous generator (PMSG)-based wind
energy conversion system (WECS) usually ignores the machine-side dynamics, instead, the …

The dc distribution power system has drawn widespread attention and rapidly developed in
recent years; however, its stability issue is one of the urgent challenges, requiring much …

Harmonic state space (HSS) is seen as an effective impedance modeling method to
precisely characterize the internal harmonic features of the modular multilevel converter …

The dc impedance model of a modular multilevel converter (MMC) is the basis for analyzing
harmonic resonances of MMC-based dc systems. As an MMC typifies a multiple harmonic …

The high-frequency resonances (HFRs) around 700 Hz and 1.8 kHz have occurred in Yu′
E project. Mechanism studies indicate that HFRs are caused by the interactions between the …
