The transient stability of an offshore-wind farm connected to the main ac grid by a high-
voltage direct current (HVDC) system depends on the control settings of the converters, the …

The modular multilevel converters (MMCs) are frequently preferred for medium and high
power energy conversion systems thanks to their modular structure and high quality output …

Modular multilevel converters (MMCs) are characterized by the multiharmonic coupling
interactions among internal dynamics. In this work, multiple-references and multiharmonic …

Multiple sub‐/super‐synchronous frequency components were detected when sub‐
synchronous oscillation (SSO) occured in permanent magent synchronous generator …

Wide-frequency range of resonances can occur in HVDC-connected DFIG-based offshore
wind farm (OWF), thus induce large harmonic distortion or endanger system stability …

This paper compares three methods, the impedance model based analysis, the positive net
damping analysis, and the open-loop modal resonance analysis. The differences and …

Sub-synchronous oscillation (SSO) incidents caused by dynamic interaction between wind
farms and power system grids can threaten safe and reliable operations. This paper …

This paper presents a new method to measure the voltage across the submodule (SM)
capacitors in a modular multilevel converter (MMC). The proposed technique requires only …

Due to the complexity of detailed models, the single-generator equivalent model (SEM) of a
wind farm is commonly used to facilitate the stability analysis. However, the adequacy of the …

Multi-terminal HVDC projects are increasingly developed in recent years to enhance the
flexibility of energy transmission. Differing from the point-to-point HVDC systems, it is more …
