A Novel Active Power Control System for Wind Turbines Capable of AGC and Primary Response

چکیده
Wind energy is increasing penetration levels on utility grids as more wind turbines are being installed. As the penetration of wind energy increases, there is motivation for wind turbines to actively control their power output to meet power set points provided by grid operators and assist with frequency regulation. This paper focuses on the development of a novel wind turbine control system that is capable of varying the turbine’s active power output upon receiving Automatic Generation Control (AGC), or power set-point, command signals to meet the system operators needs in below and above rated wind speeds. The turbine is de-rated to reach the set-points by achieving a higher than optimal tip speed ratio, storing additional inertia in the rotor which can be used to assist in frequency regulation by providing a primary/inertial response to fluctuations in grid frequency.

Model predictive control (MPC) based methods are gaining more and more attention in power converters and electrical drives. Nevertheless, high computational burden of MPC is an obstacle for its application, especially when the prediction horizon increases extends. At the same time, increasing the prediction horizon leads to a superior response. In this paper, a long horizon MPC is proposed to c...
