A Dynamic Compensation Control Strategy for Maximum Power Point Tracking Based on Feedforward Control by Using LiDAR

In this paper, we investigate the use of feedforward compensation strategies supported by LiDAR systems to enhance the capture of energy during turbine operation. In order to further improve the wind energy utilization efficiency in the low wind speed region, a new feedforward compensation control strategy based on LiDAR optimization dynamic tracking of maximum power point is proposed based on the analysis of the time contradiction in the slow dynamic characteristics of wind turbines. According to the waste of wind energy caused by the lag of speed control, this paper proposes to compensate the speed error of MPPT dynamic process by feedforward control, decrease the optimization time, increase the speed tracking accuracy of wind turbine in low wind speed regions, and finally improve the utilization efficiency of wind energy. In this paper, the co-simulation model of wind turbine simulation tool FAST and Simulink is established verifies that the control strategy can effectively improve the utilization efficiency of wind energy and realize the increase of the output power of the wind turbine.
