Abstract

This paper presents an approach that mitigates the flicker in doubly-fed induction generator (DFIG) wind turbine systems. The reactive power is controlled to compensate for the flicker from the grid-side converter (GSC). However, it is not sufficient to eliminate the flicker fully in the case of the low grid impedance ratio and the limited capacity of converters. So, a method using an energy storage system (ESS) for the output power smoothening is combined with the reactive power control to reduce the flicker. The PSCAD/EMTDC simulation results show the effectiveness of the proposed method for a 2[MW] DFIG wind turbine system.
