1. A method of control of a wind farm comprising wind turbines, each wind turbine of the wind farm, comprising an actuator for modifying an operating point including a yaw angle of each turbine with the yaw angle being an angle formed between a rotor of the turbine and a wind direction, comprising steps of:
a. acquiring power generated by each wind turbine, the wind speed, the wind speed direction, and the yaw angle of each turbine;
b. for each wind turbine, determining a wake propagation delay formed by the turbine, according to the acquired wind speed and direction, and a layout of the wind turbines within the wind farm;
c. for each wind turbine, determining a value of a reward representing an impact of control of the turbine on a sum of power generated by all the turbines of the wind farm with the reward being calculated by accounting for the determined wake propagation delay;
d. for each wind turbine, applying a reinforcement learning method to determine a target operating point of the turbine according to the determined value of a reward and a previous yaw angle; and
e. controlling the operating point of each wind turbine by applying the determined target operating point using the actuator.
