Abstract

A wind farm includes a plurality of wind energy installations, a transfer point at which electrical energy produced by the wind energy installations is transferred to a public electricity grid system and for which nominal values are preset, and a measurement sensor configured to measure electrical actual values at the transfer point. The wind farm also includes a master regulator associated with an upper control level and configured to use upper nominal values and upper actual values at the upper control level to determine a preset for a lower control level, and a plurality of submaster regulators associated with the lower control level and configured to use the preset as a lower nominal value and, on the basis of the lower nominal value and a lower actual value, determine presets for the wind energy installations. A high level of control accuracy can thus be achieved even in large wind farms.
