One-step-ahead predictive rotating speed control of wind power system based on data-drive

In view of characteristics of rotor speed control system of wind power system, the paper presented an one-step ahead predictive control method based on data-driven. Firstly, the method uses dynamic linearization technique and adopts pseudo-projection algorithm to estimate online partial derivative, and then uses the minimizing weighted performance indicators of one-step ahead to get generalized minimum variance predictive control algorithm. In order to achieve better tracking results, an adaptive item was induced to enhance output tracking capability, so make the system have stronger output response tracking. The simulation results show that the method is effective.
