Abstract
The invention relates to a method for controlling a wind farm, with A) a phase of initialization of maximization of the power generated by A1) implementation of an initial model for maximizing power generated by the wind farm via wake simulation, having initial parameters, for determining one or more initial operating points; and A2) application of these initial operating points to actuators of the wind turbines; B) real-time acquisition of wind-bin measurements; C) estimation of the parameters of the initial power-maximizing model with an estimator ESTIM based on wind-bin measurements; D) updating the initial model with the estimate; phases B), C), and D) being reiterated, and a corrected model Mn obtained; E) correcting of the maximization of the power generated.

A method of controlling a wind farm with wind turbines of the farm including at least one operating point, including a misalignment angle, that is adjustable by at least one actuator, comprising:
- A) initializing of maximization of the power generated by the farm by steps comprising:
- A1) implementing an analytical initial model, for maximizing power generated by the wind farm via simulation of wakes from the wind turbines, having initial parameters, for determining one or more initial operating points, including misalignment angles, of the wind turbines;
- A2) applying initial operating points to actuators of the wind turbines,
- B) acquiring real-time wind-bin measurements;
- C) estimating parameters of an initial power-maximizing model with an estimator based on the real-time wind-bin measurements obtained in phase B);
- D) updating the parameters of the initial model for maximizing power with the estimate obtained in C), for obtaining a corrected model, the successive steps B, C and D being reiterated n times in a first time interval P1 with a corrected model updating the parameters of the corrected model of a previous iteration being obtained in each iteration;
- and
- E) correcting maximization of the power generated by the farm, comprising:
- E1) implementing the corrected model obtained in step D) to maximize the power generated by the wind farm, for determining at least one corrected operating point, including the misalignment angle of the wind turbines;
- and
- E2) applying at least one corrected operating point to actuators of the wind turbines;
- wherein
- steps E1) and E2) are reiterated in a second time interval P2, which is longer than a first time interval P1.
