Wind energy conversion system using perturb & observe-based maximum power point approach interfaced with T-type three-level inverter connected to grid

Abstract In this paper, the performance of a permanent magnet synchronous generator (PMSG)-based wind energy conversion system (WECS) supplied to an uncontrolled rectifier-fed boost converter (BC) interfaced with three-phase T-type three-level inverter (TLI) has been analysed. The proposed WECS involves three converters, namely rectifier that is used for from AC DC; BC by PMSG-fed enhance voltage gain; and grid-connected TLI eliminate power-quality issues synchronization grid current. main goal research model control using d–q frame regulating DC-link transferring generated power grid. Furthermore, perturb & observe (P&O)-based maximum point (MPP) approach recommended keep track MPP PMSG-based under constant variable speeds. computationally modelled, simulated validated speeds MATLAB® Simulink®. It confirmed P&O-based ensures varying speeds, total harmonic distortion current value 3.18%, which within IEEE-519 limits. synchronization, factor maintained at unity avoid issues.
