Accurate aggregated modelling of wind farm systems in modified sequence domain for stability analysis
Zong, Haoxiang; Lyu, Jing; Cai, Xu; Zhang, Chen; Molinas Cabrera, Maria Marta; Rao, Fangquan (Peer reviewed; Journal article, 2019)With the wind power penetration rate continuously rising, a suitable wind farm model considering both accuracy and simplicity is required for power system stability analysis. To accomplish this goal, an accurate aggregated ... -
Control of a Type-IV Wind Turbine with the Capability of Robust Grid-Synchronization and Inertial Response for Weak Grid Stable Operation
Sang, Shun; Zhang, Chen; Cai, Xu; Molinas Cabrera, Maria Marta; Zhang, Jianwen; Rao, Fangquan (Journal article; Peer reviewed, 2019)With the increasing penetration of wind power, the effective inertia of the power system reduces. Besides, a series of interactive instability issues including sub-synchronous oscillations and harmonic oscillations were ... -
Mimo impedance based stability analysis of DFIG-based wind farm with MMC-HVDC in modifed sequence domain
Zong, Haoxiang; Lyu, Jing; Zhang, Chen; Cai, Xu; Molinas Cabrera, Maria Marta; Rao, Fangquan (Chapter, 2019)The modular multilevel converter (MMC) based high-voltage direct current (HVDC) transmission is widely applied for the large-scale wind farm integration making its interaction stability analysis especially significant. ... -
Modified sequence domain impedance modelling of the modular multilevel converter
Zong, Haoxiang; Lyu, Jing; Zhang, Chen; Molinas Cabrera, Maria Marta; Cai, Xu; Rao, Fangquan (Chapter, 2019)The accurate sequence impedance model of the modular multilevel converter (MMC) is essential for the precise stability analysis of various MMC-based interconnected systems. This paper presents a modified sequence impedance ...
