Abstract

The wind farm's power control structure and process are introduced in this paper. Fristly, a linearized power control model for model predictive control is established with an analysis of the dynamic characteristics of each control object within the wind farm. Subsequently, a strategy for coordinated and predictive control of active and reactive power models in wind farm is proposed. This strategy aims to minimize the load change of the wind turbine transmission chain, the voltage variation across each wind turbine, and the active and reactive power losses within the wind farm. Furthermore, the model predictive control algorithm is elucidated. Finally, a wind farm simulation model is established within Matlab/Simulink. Simulation results demonstrate that the proposed control strategy can accurately adhere to the power generation tasks and voltage commands issued by power grid dispatching. Concurrently, it reduces the active and reactive power losses of the wind farm and the drive train fatigue load of each wind turbine, enhancing the operational safety and economy of the wind turbine.
