Wind farm controller, controlled units and method for transmitting control variables from the wind farm controller to the controlled units

A method for transmitting control variables from a controller to wind power installations or energy stores, comprising:

• determining a first control variable component;
• determining, by the controller, a second control variable component;
• outputting the first control variable component in a first data packet;
• outputting the second control variable component in a second data packet;
• receiving, by at least one wind power installation or energy store, the first data packet including the first control variable component;
• receiving, by the at least one wind power installation or energy store, the second data packet including the second control variable component;
• and
• determining, by the at least one wind power installation or energy store, a control variable from the first control variable component and the second control variable component,
• wherein the first data packet has a first receiver address that is assigned to the at least one wind power installation or energy store and to at least one further wind power installation or energy store, and the second data packet has a second receiver address that is assigned to the at least one wind power installation or energy store, and
• wherein first data packets having respective first controlling control variable components are sent more frequently than second data packets having respective second controlling control variable components.
