Controlling of PMSG-Assisted Wind Energy Conversion System with Maximum Power Tracking Technique

摘要

This paper develops a dynamic model of small-scale wind energy conversion system (WECS) based on diode bridge rectifier and permanent magnet synchronous generator (PMSG). The simple and effective perturb and observe (P&O) algorithm has been proposed for extracting maximum power point tracking (MPPT) of wind turbine (WT) in the moderate-to-cutout wind speed region by sensing input parameters of DC-DC buck-boost converter. The MPPT algorithm in addition to the DC-DC converter is being simulated in MATLAB/Simulink software. The obtained characteristics show the effectiveness of P&O MPPT technique for extracting maximum power from the wind and delivering it appropriately to the resistive load.
