Abstract
A method for adjusting a power parameter of a wind turbine is disclosed. The method includes determining a load parameter indicative of a mechanical load of the wind turbine; estimating a turbulence of a wind speed based on the determined load parameter; and adjusting the power parameter relating to a power of the wind turbine based on the estimated turbulence. A system for adjusting a power parameter of a wind turbine is also described.

A method for adjusting an electrical power parameter of a wind turbine, the method comprising:
- determining a load parameter indicative of a mechanical load of the wind turbine;
- estimating a turbulence of a wind speed based on the determined load parameter;
- updating a power lookup table defining a power of the wind turbine depending on the rotor speed, the power lookup table is updated by using the estimated turbulence;
- adjusting the electrical power parameter based on the load parameter, the estimated turbulence and a minimal power supplied from the power lookup table.
A system for adjusting an electrical power parameter of a wind turbine, the system comprising:
- a module configured for determining a load parameter indicative of a mechanical load of the wind turbine;
- a rotor speed sensor configured for detecting a rotor speed;
- a power lookup table defining a power of the wind turbine via a relationship between the rotor speed and an estimated turbulence, the estimated turbulence based on the determined load parameter, the power lookup table configured to receive the rotor speed and the estimated turbulence in order to update the power lookup table;
- and
- a controller configured for adjusting the electrical power parameter relating to an electrical power of the wind turbine based on the determined load parameter, the estimated turbulence and a minimal power supplied from the power lookup table.
