Abstract: Wind power plants are becoming popular renewable energy sources in the distribution system, it employs Doubly Fed Induction Generator (DFIG) to generate power based on wind conversion. This paper highlights issues of voltage stability check during various load parameters which include short and long transmission lines in both grid- connection and Islanding scenarios, THD and load fluctuations. Basically this study develops a framework to carryout the investigation on electrical variables and therefore voltage profile between wind stations and load centers are realized. A microgrid based small signal analysis is performed in the laboratory using MATLAB and different comparisons are made and simulation case studies are presented.

Keywords: doubly fed induction generator (DFIG); voltage source converter; voltage stability, THD
