Embodiment Construction

[0063] figure 1 A wind energy installation 100 of a wind farm according to the invention is shown.

[0064] For this purpose, the wind energy installation 100 has a tower 102 and a nacelle 104 . An aerodynamic rotor 106 with three rotor blades 108 and a fairing 110 is arranged on the nacelle 104 . During operation, the rotor 106 is set in rotational motion by the wind and thereby drives a generator in the nacelle 104 . As a result, the generator generates an electrical current, which is applied by means of a full power converter to a wind energy installation transformer, which is connected to the wind farm grid.

[0065] figure 2 A schematic configuration of a wind park 1000 according to the invention in one embodiment is shown.

[0066] The wind farm 1000 comprises a plurality of wind energy installations 1100, as for example at figure 1 As shown in , the plurality of wind energy installations are connected to each other via a common wind park grid 1200 .

Abstract

The invention relates to a method for open-loop control of an electrical distribution grid having a rated grid voltage, in particular in a critical grid situation, wherein a grid control centre is provided for open-loop control of the electrical distribution grid and the electrical distribution grid comprises at least one closed-loop control region which includes a plurality of spatially separate wind farms. The method comprises the steps of: querying available capacities of the wind farms, in particular on the basis of a weather forecast; defining a closed-loop control node within the closed-loop control region, in particular on the basis of the queried available capacities, preferably by the grid operator; grouping a number of wind farms on the calculated closed-loop control node to form a wind-energy plant on the basis of the queried available capacities and / or a probability distribution of the available capacity; open-loop control of the wind-energy plant, in particular by the grid control centre, by means of a wind-energy-plant open-loop control unit such that a required voltage quality and / or frequency stability and / or interruption-free availability is provided in the closed-loop control region.

Description

technical field [0001] The invention relates to a method for controlling an electrical distribution network, in particular by means of a plurality of wind parks, and to such wind parks. Background technique [0002] Distribution grids, such as the German transmission grid or the European Union grid, usually have a plurality of generators and consumers. [0003] In order to be able to better regulate the load flow between generators and consumers, distribution networks are therefore usually divided geographically into regulation areas and assigned to individual operators, so-called grid operators. [0004] This results in particular in that each control zone itself is rigidly defined and in particular has a rigid generator-consumer structure. [0005] The actual control of these regulated areas or sections of the distribution network then takes place by means of so-called grid control centers, which are basically set up to control the generators of the regulated areas.
