Title
Impedance Modeling of DFIG Wind Farms With Various Rotor Speeds and Frequency Coupling
Abstract
The oscillation phenomenon frequently occurs in large-scale grid-connected doubly-fed induction generators (DFIG) wind farms and the impedance-based analysis has gradually become a widely used method to analyze the wind power oscillation issues. The rotor speed of each wind turbine (WT) is usually different as an important factor to determine the operating point and affect the output impedance. This brief develops a DFIG wind farm impedance model considering different rotor speeds. The impedance of each WT is firstly obtained according to various rotor speeds and all the WTs are aggregated considering the complex frequency coupling effects to describe the overall wind farm impedance. The comparison between the simplified aggregation method of wind farms and the proposed model is given to indicate that the proposed model can provide more accurate modeling and stability analysis results.
