“…In the case of wind power fluctuation and inaccurate system model, the authors Sánchez et al in [7] utilized the model predictive control (MPC) technology to test the control ability of reactive power of a voltage source converter high-voltage direct current network. In Wu et al's work [8], the reactive power control of a wind farm was realized via several switchable and variable reactors and transformers to coordinate the control voltage. For large wind farms, distributed MPC was used in Liu et al's work [9] to realize the coordination and optimization between the thermal plant, the hydro plant, and the wind farm in order to realize load frequency control.…”

Due to the uncertainty and volatility of wind speed, its natural output power also exhibits strong volatility. In order to avoid the negative effects of the excessive fluctuation of the output power of wind turbines in the wind farm and the power grid, it is very important to accurately predict and reasonably plan and control the output power of the wind farm. Model predictive control (MPC) is a type of advanced control method that can deal with a multi-input multi-output nonlinear system. Compared to the traditional proportional integral derivative control, MPC is more suitable for the complex wind farm model and exhibits good control performance, and has been gradually applied to control the wind power in wind farms. In this article, we have summarized the application of the MPC technology in the prediction and control of wind power in a wind farm, analyze the application of the MPC technology, including MPC, multi-objective MPC, nonlinear MPC, and distributed MPC, in the wind farm power control with different optimization objectives. In addition, the optimization of the active and reactive power of wind farms has also been discussed in detail. Furthermore, some hot topics in the current research, such as the multi-objective optimization problem of coordinating the maximum power and reducing the fatigue load and power smoothing control problem, have been summarized. Finally, the existing problems of MPC applied to wind power systems have been discussed.
