This paper aims to reduce dc-link voltage fluctuations in variable speed wind energy conversion system based on permanent magnet synchronous generator (PMSG). A flywheel energy storage system (FESS) which is connected to a squirrel cage induction machine is used for dc-link of PMSG. FESS has been applied to reduce the fluctuations of the injected power into the network and to regulate the power flow, which has been carried out by sending/receiving power from FESS when there is an excess/deficiency of the network power. Type-II fuzzy logic controller is proposed to improve the PMSG performance and dc-link voltage control, that its performance has been compared with PI controller and type-I fuzzy logic controller. The grid connected converter is used to separately control the active and reactive power for achivement of unity power factor. The dynamic model of the proposed system has been simulated using MATLAB-Simulink software and the obtained results prove the effective performance of the proposed controller. |
