Wind farm power control based on matrix reflecting a power load distribution between individual wind turbines

A superordinate control system for controlling the operation of a wind farm comprising a plurality of wind turbines, the superordinate control system comprising

• a definition unit for defining a setpoint vector, wherein each component of the setpoint vector represents an individual power setpoint of one of the plurality of wind turbines;
• a determination unit for determining a dependency matrix, which reflects a desired power generation distribution between different wind turbines of the plurality of wind turbines;
• a calculation unit for calculating a power reference vector by multiplying the dependency matrix with the setpoint vector, such that the power reference vector comprises a coordinated power setpoint for each wind turbine;
• and
• a control unit for controlling the operation of the wind farm based on the calculated power reference vector,
• wherein calculating the power reference vector further comprises adding a correction vector to the result of multiplying the dependency matrix with the setpoint vector, and
• wherein the correction vector comprises a power correction value for each wind turbine, whereby each power correction value is indicative for a requested time rate of change of the total power output of the wind farm.
