English Description:
Application backgroundTo meet the strict criteria of grid codes for the integrated wind farm with the grid has become a major point of concern for engineers and researchers today. Moreover voltage stability is a key factor for the stable operation of grid connected wind farm during fault ride through and grid disturbances. This paper investigates the implementation and comparison of FACTS devices like STATCOM and SVC for the voltage stability issue for DFIG-based wind farm connected to a grid and load. The study includes the implementation of FACTS devices as a dynamic voltage restorer at the point of common coupling to maintain stable voltage and thereby protecting DFIG-based wind farm interconnected powers system from isolating during and after the disturbances. The power system mo
