This paper addresses the small-signal stability of voltage-controlled modular multilevel
converters (MMCs) feeding linear ac systems. By using the harmonic state-space (HSS) …

The high-voltage dc (HVDC) systems are appearing more and more, and it is becoming a
requirement that the HVDC voltage-source converters (VSCs) operate both as an inverter …

To eliminate the low-frequency oscillation (LFO) phenomenon in the vehicle-grid system of
high-speed railways, a single-phase cascaded H-bridge multilevel active power filter (APF) …

Field experiences have shown that sub-synchronous oscillations (SSOs) can occur in direct-
drive wind farms with VSC-HVDC (DDWFV) systems. In light of this, a dynamic mathematical …

This paper investigates a new type of subsynchronous oscillation (SSO) event observed in a
real-world doubly fed induction generator (DFIG)-based wind power plant (WPP) connected …

在大规模风电场并网系统中, 经串联补偿, 弱交流系统或HVDC 并网均有可能引发风电机组的次
同步振荡, 但产生机理与相关特性各不相同. 文章首先介绍了大规模风电场经串联补偿 …

This paper investigates the stability of a modular multi-level converter (MMC) based HVDC
system connected to a weak ac grid. Impedance analysis is used to study the interactions …

The large integration of modular multilevel converters (MMC) has introduced stability issues.
The impedance-based stability analysis method is widely adopted, where the impedance …

The stability of an offshore wind power network connected through a high-voltage dc
(HVDC) transmission line can be challenging since a strong ac collection (ACC) bus might …

Following a converter outage in a Multiterminal dc (MTDC) for offshore wind farm integration,
the conventional droop control shares the power mismatch to minimize the impact on the …
