Abstract :
This paper presents the transient stability improvement of a grid connected wind farm using doubly-fed induction machine (DFIM) based flywheel energy storage system (FESS). The control strategy of the FESS relies on a frequency converter with insulated gate bipolar transistors (IGBTs) using cascaded proportional-integral (PI) controllers. These PI controllers are used to control the rotor side converter (RSC) and the grid side converter (GSC) of the DFIM. The detailed modelling and the control strategy of the system under study are investigated. The effectiveness of the proposed control strategy is tested under a severe symmetrical fault condition. The validity of the system is verified by the simulation results which are carried out using PSCAD/EMTDC environment.
