Field Oriented Control for Efficient and Simplified Wind Power Generation Using DFIG

Abstract

This paper presents the modeling, simulation, and performance analysis of a Doubly-Fed Induction Generator (DFIG)-based wind energy conversion system (WECS) using Field-Oriented Control (FOC) due to its structural simplicity and ability to meet desired dynamic performance requirements. The study includes comprehensive dynamic modeling of key WECS components from the wind turbine to the grid interface developed in a MATLAB/Simulink environment. The FOC strategy is applied to independently regulate active and reactive power, ensuring effective energy conversion and stable grid integration. Simulation results demonstrate the system’s capacity to maintain steady active and reactive power output and achieve a low Total Harmonic Distortion (THD) of 4.57% in the grid voltage, indicating improved power quality. The novelty of this work lies in its system-wide modeling and performance validation of an FOC-controlled DFIG system in a compact, simulation-based approach suited for low-cost, efficient wind power applications. The results show that a well-implemented standard FOC approach can achieve effective control without the need for algorithmic complexity.
