Abstract
This paper investigates the control strategy for extracting stable output power and regulating DC-link voltage in a permanent-magnet vernier generator (PMVG)-based wind turbine system (WTS). To do this, the dynamical model of PMVG-based WTS is constructed. Then, in order to maximize output power, an integral sliding mode controller (ISMC) for the machine-side converter (MSC) is presented, which allows the generator to operate at an optimal speed at varying wind speeds. At the same time, the ISMC is designed for a grid-side converter (GSC) to protect the DC-link from over-voltage and procure steady output power during rotor speed and grid voltage varying conditions. Also, the exponential reaching law is employed to ensure stable output power and reduce the DC-link voltage chattering during various wind speed conditions. Finally, the simulation and experimental results are presented to show the effectiveness and feasibility of the designed control scheme for the 5 kW PMVG-based WTS set-up.
