## Abstract

A method for providing data sets for the units, in particular wind turbines, of a wind park. The wind park is divided into at least two groups, wherein at least one group, a plurality of groups or all groups in each case have at least two units. An individual data set is first generated in each case for each of the groups. A data packet which comprises at least the generated individual data sets is then generated and the data packet is then transmitted to all units of the wind park. A wind park controller, a method for receiving a data set, a unit and a wind park is also provided.

## Claims

### Claim 1

A method comprising:
providing data sets for a plurality of units of a wind park, wherein the wind park is divided into at least first and second groups, and wherein at least one group of the first and second groups comprises at least two units, the providing comprising:
generating an individual data set in each case for each of the at least first and second groups;
generating a data packet comprising at least the generated individual data sets and a global data set for the at least first and second groups, wherein:
active power controlling control variables are generated as the generated individual data sets,
reactive power controlling control variables are generated as the global data set, and
the global data set is the same for the at least first and second groups; and
transmitting the data packet to the plurality of units of the wind park.

### Claim 2 (depends on 1)

The method as claimed in claim 1, wherein generating the individual data set includes generating the individual data sets with one or more of: control signals, a controlling control variable, and a reserve power.

### Claim 3 (depends on 1)

The method as claimed in claim 1, wherein the plurality of units feed energy for a first time into a connected network or are connected to the network before a predefined date are assigned to the first group and at least the second group contains the remaining units of the wind park.

### Claim 4 (depends on 1)

The method as claimed in claim 1, wherein individual standard values are provided for the plurality of units, wherein the standard values have same values for the plurality of units of a same group of the first and second groups and have different values for different groups of the first and second groups.

### Claim 5 (depends on 1)

A wind park controller comprising circuitry configured to carry out the method as claimed in claim 1.

### Claim 6 (depends on 5)

A wind park comprising the wind park controller as claimed in claim 5 and the plurality of units.

### Claim 7 (depends on 1)

The method as claimed in claim 1, further comprising:
receiving the transmitted data sets by the plurality of units of the wind park, the receiving comprising:
receiving the data packet;
extracting at least the respective individual data set from the data packet for the respective group to which the unit is assigned; and
using the extracted data set in the unit.

### Claim 8 (depends on 7)

The method as claimed in claim 7, wherein the individual data set contains control signals used in the unit to control the unit, or the individual data set comprises a controlling control variable.

### Claim 9 (depends on 8)

The method as claimed in claim 8, wherein the controlling control variable comprises an active power controlling control variable or a reactive power controlling control variable used to control the unit.

### Claim 10 (depends on 7)

The method as claimed in claim 7, wherein the unit extracts the global data set and uses the extracted global data set in the unit.

### Claim 11 (depends on 10)

The method as claimed in claim 10, wherein the active power controlling control variable and the reactive power controlling control variable are used to control the unit.

### Claim 12 (depends on 7)

The method as claimed in claim 7, wherein the unit is assigned to a first group if the unit has fed energy into a connected network for the first time or was connected to the network before a predefined date.

### Claim 13 (depends on 7)

The method as claimed in claim 7, wherein the wind turbine has same standard controlling control variables as further units of a same group and different standard controlling control variables than the units of other groups.

### Claim 14 (depends on 7)

A wind turbine, STATCOM unit, or energy store configured to carry out the method as claimed in claim 7.

### Claim 15 (depends on 7)

The method as claimed in claim 7, wherein the unit is assigned to at least one of the first and second groups of a wind park, wherein both the first and second groups each comprise at least two units.

### Claim 16 (depends on 1)

The method as claimed in claim 1, wherein the plurality of units are a plurality of wind turbines.
