Here again, the question arises: who is responsible for these different possible restrictions, of which up to 28 or more can be identified, and what share of the loss of revenue is borne by which restrictions, i.e. who has to What share bears the costs incurred
Therefore, estimating "P-Available" based on measured wind speeds leads to an overestimation of available farm power, since wind farm effects are not considered

Embodiment Construction

[0103] figure 1 A schematic diagram of a wind energy facility 100 is shown. The wind energy installation 100 has a tower 102 and a pod 104 on the tower 102 . An aerodynamic rotor 106 with three rotor blades 108 and a shroud 110 is arranged on the nacelle 104 . The aerodynamic rotor 106 is brought into rotational motion by the wind during operation of the wind energy installation and thus also rotates the aerodynamic rotor or rotating part of the generator, which is directly coupled to the aerodynamic rotor 106 . A generator is provided in the nacelle 104 and produces electrical energy.

[0104] figure 2 A wind farm 112 is shown with exemplary three wind energy installations 100, which can be the same or different. Thus, the three wind energy installations 100 essentially represent any number of wind energy installations of the wind farm 112 . The wind energy installation 100 supplies its power, ie in particular the generated electrical current, via the farm grid 114 . I...

Abstract

The invention relates to a method for determining the available power of a wind park (112). The wind park comprises multiple wind turbines (100) with a rotor (106) comprising rotor blades (108) with adjustable blade angles. The invention additionally relates to a wind park (112) which is designed to carry out the method for determining the available power. The method has a step of providing a shading matrix (200) which determines at least one wind speed acting on each of the wind turbines (100) of the wind park (112) as a function of at least one wind speed and wind direction and a wind park throttling using a park run-on model. The method according to the invention allows the available power of a wind park (112) to be determined precisely even when the wind park (112) is operated with throttled power.

Description

technical field [0001] The present invention relates to a method for determining the available power of a wind farm. The invention also relates to a wind farm set up for carrying out a method for determining available power. Background technique [0002] Wind energy installations are known and by means of which electrical power is generated from the wind and fed into a power supply network. The electrical power to be fed in fluctuates for various reasons, eg throttling is required due to grid constraints. [0003] Consequently, grid operators and facility operators increasingly require that the facility determine so-called "available power", which may also be referred to as "P-available". While grid operators are generally interested in what regulation reserves are available in the grid, operators are primarily interested in how much revenue is lost due to different constraints. However, only knowing the power contained in the wind does not help the grid operator if the f...
