State-Space Model of the Wind Energy Conversion System Integrated to Power Grid Using Type-4 Wind Turbine/PMSG

In this paper, the model and simulation in state space of a wind energy conversion system (WECS), using the type-4 wind turbine topology is presented. The model in state space of a wind turbine (WT) with direct-drive permanent magnet synchronous generator (PMSG) via full scale back-to-back converter integrated into the power grid using a RL filter is described. The particular interest in this work is to address the dynamic study of variable-speed wind, evaluating the performance of proposed control devices. The obtained results in the case study are validated against the obtained response with Matlab/Simulink
