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 DFIG (Double-Fed Induction Generator) 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 mountainous areas can be reviewed. Secondly, the simplified modeling method for wind farm could be briefly discussed. 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 has been 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 involving the variation of wind speed distribution, cut-in wind speed, and cut-out wind speed. The discussions and conclusions would be useful for dynamic characteristics analysis of high-density wind power integrated power system in mountain areas.
