## Abstract

A method of controlling a wind turbine includes the step of boosting the output power of the wind turbine above the nominal power of the wind turbine, according to a boost operational function representing a boost level for the wind turbine. The boost operational function is a crescent function of an operational variable at least between a first threshold value and a second threshold value of the operational variable.

## Claims

### Claim 1

A method of controlling a wind turbine, the method comprising:
boosting an output power of the wind turbine above a nominal power of the wind turbine, according to a boost operational function representing a boost level for the wind turbine, the boost operational function being a crescent linear function of a turbulence intensity at least between a first threshold value and a second threshold value of the turbulence intensity, wherein the boost operational function is defined at a constant pitch angle of at least one blade between the first threshold value and the second threshold value.

### Claim 2 (depends on 1)

The method according to claim 1, wherein the boost operational function is constant between the second threshold value and a third threshold value of the turbulence intensity.

### Claim 3 (depends on 1)

The method according to claim 1, wherein the boost operational function is linearly decrescent between a third threshold value and a fourth threshold value of the turbulence intensity variable.

### Claim 4 (depends on 1)

The method according to claim 1, wherein the pitch angle is increased between the second threshold value and a third threshold value.

### Claim 5 (depends on 1)

The method according to claim 1, wherein the first boost operational function is obtained at the constant pitch angle by adjusting the output power according to a look-up table.
