Cooperative Control for Wind Turbines Based on Hamilton System Under Limited Input

Aiming at the complex nonlinear system such as wind power generation, under the condition of limited input, how to achieve the maximum wind energy capture under variable wind speed operation is researched, so that the wind turbines can work on the best power curve to improve the utilization rate of wind energy, and the coordinated control of multiple wind turbines is explored. Based on the Hamilton model of wind power generation systems, a preset + cooperative controller is designed. The preset controller is used to capture the maximum wind energy for each wind turbine. The cooperative controller is designed to realize the cooperative control of multi wind turbines. In the design of cooperative controller, the saturation function processing method of the nonlinear sector method is used, and limited input is realized. Simulation results show that under the condition of variable wind speed operation and limited input, the wind turbine can operate at the desired speed, which not only realizes the maximum wind energy capture under variable wind speed conditions, but also realizes the coordinated control of multi wind turbines against input saturation.
