Embodiment Construction

[0042] image 3 An embodiment of the invention is shown schematically for a plurality of networked wind turbines 1 . The wind turbines 1 add energy to the utility grid at the PCC 13 through the interconnected, wind turbine common electrical grid 6 .

[0043]The central wind turbine control system 8 receives at least one control parameter, such as one or more setpoint values ​​12 , from the utility grid operator.

[0044] Each individual networked wind turbine 1 is connected to the central wind turbine control system 8 via a data connection 14 for the distribution of data between the control system 8 and the individual wind turbines 1 . For one embodiment of the invention, the data connection 14 is an integrated SCADA system, and for other embodiments of the invention, the data connection is a separate data connection for transmitting data to a single wind turbine and Receive data from a single wind turbine.

[0045] According to various embodiments of the present invention,...

Abstract

The invention relates a method for controlling a common output from at least two wind turbines comprising the steps of receiving at a central wind turbine control system at least one set point value of a set point parameter from a utility grid operator, and at least one operational value of a operational parameter from at least one of said wind turbines Furthermore the method comprises the steps of stablishing a cost function equation comprising at least one function variable reflecting an operational parameter of said wind turbines and said received set point parameter, solving the cost function equation with respect to said at least one function variable to find an extremum for said cost function, calculating weighted operational parameter set points for each of said wind turbines from the obtained solution, and controlling at least one of said wind turbines in relation to said weighted operational parameter set points. The invention also relates to a central wind turbine control system, a wind park and a cluster of wind parks.

Description

technical field [0001] The present invention relates to a method for controlling the common output of at least two wind turbines. Furthermore, the present invention relates to a central wind turbine control system, a wind farm and a group of wind farms. Background technique [0002] Wind farms that include multiple wind turbines are often used to support the stability of the utility grid by conforming to grid code settings and by being viewed as a unified and tunable power plant that can The active current, reactive current, etc. are supplied to the public transmission network in a controlled manner. Utility grid operators can improve the stability and efficiency of the utility grid. [0003] In a wind farm, the wind turbines are controlled by a wind farm control system. European patent application EP1790851 describes a method for controlling a wind farm comprising a central processing and control unit connected to a wind turbine. Data is received from at least one upstr...
