Performance Evaluation of New Series Connected Grid-Side Converter of Doubly-Fed Induction Generator

Increasing penetration of the large wind farm in the system has forced the power system policy makers to develop new electricity grid codes which are required for the wind power generator to fulfill the same requirements as conventional power plants. In this paper, a series connected grid side converters with conventional doubly-fed induction generator (DFIG) scheme is explored to suit the grid code requirements (GCRs) during static and dynamic conditions. A dynamic model and control structure for the series architecture are developed and the performance of the system along with the controller is analyzed for voltage sag condition. Reactive power support capability of series converter during steady state condition is also demonstrated.
