摘      要:Advanced prediction technologies have enabled model predictive control (MPC) to be a potential powerful method for controlling wind turbines (WTs). However, the MPC technique available for the yaw control system of WTs is lacking. In this study, we propose a novel MPC using finite control set and multi-step prediction models for the yaw control system and solve the optimal problem using an exhaustive search method. Then, the proposed method is demonstrated by the simulation tests and the achievable performance of the yaw control system under different prediction horizons is investigated. Finally, our results show that, along with the extended prediction horizon, the power production performance is enhanced while maintaining the same yaw actuator usage.
