Abstract

This paper presents an improved Direct Power Control (DPC) approach applied to the Grid-Side Converter (GSC) of a wind-driven Permanent Magnet Synchronous Generator (PMSG). The proposed method modifies the conventional switching table by incorporating the errors of the direct and quadrature current components along with the filtered grid voltage vector. The objective is to enhance steady-state behavior and reduce power fluctuations. A comprehensive simulation model is developed in MATLAB/Simulink to assess system performance under different loading conditions and varying wind speeds. Furthermore, the system is evaluated under disturbance conditions, and a comparative validation is performed using classical DPC, Field-Oriented Control (FOC), and Space Vector Pulse Width Modulation (SVPWM)-based FOC. The obtained results confirm that the proposed method achieves improved harmonic and steady-state performance while preserving a relatively simple control structure. Moreover, the Total Harmonic Distortion (THD) of both grid voltage and current remains below 5% at the Point of Common Coupling, complying with IEEE-519 standards. These findings confirm the robustness and effectiveness of the modified DPC scheme in improving power quality and ensuring stable operation of PMSG-based Wind Energy Conversion Systems under variable operating conditions.
