ISVM Control and Virtual DC Bus Voltage Regulation for Direct Matrix Converter for Wind Energy Conversion System
2023 IEEE International Conference on Advanced Systems and Emergent Technologies (IC_ASET)(2023)
Abstract
In this paper, the static and dynamic performance of a wind energy conversion system (WECS) based on a permanent magnet synchronous machine (PMSM) coupled to an electrical network via a three-phase direct matrix converter (DMC) has been studied. The considered system control is based on two techniques: the voltage-oriented control (VOC) for the grid side and the direct power control (DPC) for the PMSM side, which are combined by the indirect space vector modulation (ISVM) technique. This control strategy is also equipped with an MPPT algorithm to increase the wind power and to provide the desired references for the (VOC-DPC) controller, and another controller to adjust the virtual DC bus voltage to produce the reference current to the VOC controller. The aim of the wind system control strategy is to inject active power into the electrical grid with a unit power factor (UPF). The control strategy adopted for the WECS system is validated through numerical simulations under “Matlab/Simulink”. Simulation results show the dynamic responses with good accuracy and excellent performance, justifying the effectiveness technique used to control the integrating DMC converter in a WECS system.
