Dynamic Sequential Model Predictive Control of Three-Level NPC Back-to-Back Power Converter PMSG Wind Turbine Systems

With the development of the high-power wind turbine systems, permanent-magnet synchronous generator with direct-drive configuration is attractive for high-power wind energy conversion systems. As one of the key technologies of wind energy conversion, control technology plays an important role in the performance of wind power systems. Due to its excellent dynamic performance and multi-objective control, model predictive control has become an alternative and promising method. However, the cumbersome process of tuning weighting factors is its main drawback. In this work, a new control structure, as so-called dynamic sequential model predictive control is proposed. It avoids using weighting factors and overcomes the drawbacks of sequential model predictive control. The proposed control strategies are validated and compared with the sequential model predictive control in Plecs simulation.
