Abstract

A simple and efficient model predictive control technique for a six-phase permanent magnet synchronous generator-based wind energy system with fixed switching frequency is presented in this paper. The power converter interface to the grid features a dual diode-bridge rectifier, followed by a three-channel (3C) boost converter and a two-channel grid-tied voltage source inverter (2C-VSI). The proposed control technique is divided into two decoupled and independent control loops: the first corresponds to a deadbeat current control for the 3C-boost converter, while the second is a modulated model predictive current control for the 2C-VSI. The maximum power point tracking is achieved through the regulation of inductor currents of 3C-boost converter, whereas the 2C-VSI is in charge of grid active and reactive power control with excellent power quality. The proposed control techniques ensure fixed switching frequency and interleaved operation for the 3C-boost converter and 2C-VSI under a wide dynamic range, leading to less steady-state errors and fast transient response with effective distribution of power among the channels. To evaluate the proposed control technique, dynamic simulation results are presented for a 1.5 MW commercial wind turbine under varying wind speed conditions.
