基于模块化多电平换流器(modular multilevel converter, MMC) 的柔性直流输电技术(MMC-
HVDC) 已成为大规模, 远距离海上风电场并网的理想解决方案. 由于MMC 自身的结构特点 …

Field experience has shown that subsynchronous oscillation and harmonic resonance can
occur between wind farms (WFs) and high voltage dc (HVdc) systems. The oscillations can …

Emerging sub-synchronous interactions (SSI) in wind-integrated power systems have added
intense attention after numerous incidents in the US and China due to the involvement of …

For high-voltage direct-current (HVDC) transmission, the strength of the ac system is
important for normal operation. An ac system can be considered as weak either because its …

This study presents an improved means of direct power control (DPC) of grid-connected
voltage-sourced inverters (GC-VSIs) when the network voltage is unbalanced. The DPC is …

Power systems are experiencing a rapid and dramatic transformation driven by the massive
integration of nondispatchable renewable energy sources, such as wind and solar, and …

Resonances can limit power transfer in a voltage-source converter-high voltage dc (VSC-
HVDC) system. The objective of this paper is to develop impedance models for the rectifier …

Estimation of critical control parameters is a desirable tool feature for stability analysis and
impedance shaping of high voltage dc (HVdc) connected wind farms. Accurate estimation of …
