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

Grid-tied voltage source inverters using LCL filter have been widely adopted in distributed
power generation systems (DPGSs). As high-order LCL filters contain multiple resonant …

Representation of ac power systems by frequency-dependent impedance equivalents is an
emerging technique in the dynamic analysis of power systems including power electronic …

Stability of a grid-connected inverter depends on the ratio of the grid impedance to the
inverter impedance. Since the grid impedance changes during normal power system …

This paper investigates the stability and control of offshore wind farms employing medium-
voltage ac collection and high-voltage dc (HVDC) transmission to the onshore power grids …

Due to the advantages of superior harmonics attenuation ability and reduced size, the LCL
filter has been widely adopted to interface between the inverter and the grid for improving …

Impedance-based method is an effective method to analyze the system stability. Based on
the impedance stability theory, a doubly fed induction generator (DFIG) based wind power …

The increasing penetration of renewable energy resources, such as wind and solar, is
changing AC grid dynamics. Potential dynamic stability issues such as small signal …

Sequence impedance models are presented for type-III wind turbines that use doubly fed
induction generators and back-to-back voltage source converters. The models, presented in …

Grid impedance and the output impedance of grid-connected inverter are important
parameters for the operation of grid-connected systems, such as solar, wind, and other …
