Method for controlling a wind farm by means of an optimization method

A wind farm method of control of turbines of the wind farm including an actuator for modifying an operating point of a yaw angle of the turbines, wherein the yaw angle is formed between a rotor of each wind turbine and a wind direction of wind blowing on the wind farm comprising:

• a. acquiring a wind speed and wind direction distribution of a site of the wind farm in real time;
• b. constructing a wind farm model, the wind farm model relating the wind speed and the wind direction and the operating point of each turbine for power generated by the wind farm in which the wind farm model accounting for a wake effect;
• c. constructing for each wind turbine a load model, the load model relating the wind speed and wind direction and the operating point for each turbine to a load on at least one component of the turbine;
• d. determining for each wind turbine, a target operating point which optimizes an expected value of power generated by the wind farm determined by the wind farm model for the acquired wind speed and the acquired wind direction distribution, the expected value of the load on each turbine which is determined by the load model of each turbine for the acquired wind speed and acquired direction distribution which is a parameter of a cost function of an optimization method to be optimized or a constraint of the method which optimizes an optimization method accounting for the wind speed and the wind direction in real time;
• and
• e. controlling the target operating point of each wind turbine by applying the determined target operating point to the actuator for modifying the yaw angle of the turbine.
