Modeling of DFIG based wind farm considering temporal and spatial non-uniformity of wind speed in mountainous region and its applicability analysis

In order to improve the validity and accuracy of wind farm integrated power system dynamic analysis in high-altitude mountainous region, it is necessary to study on modeling of double-fed induction generator (DFIG) based wind farm considering non-uniformity of wind speed in mountainous region and its applicability analysis. Firstly, the wind speed characteristics of wind farm in high-altitude mountain can be reviewed. Secondly, the simplified modeling method for wind farm could be discussed briefly. Thirdly, a detailed modeling method for wind farm based on a user-defined model with temporal and spatial distribution of wind speed using PSS/E is proposed. A case study is carried on a high-altitude mountainous wind farm in Guizhou which may analyze the applicability of detailed model and simplified model by the comparisons in three scenarios involving the variation of wind speed distribution, cut-in wind speed, and cut-out wind speed.
