Abstract
A method of operating at least one wind turbine including: receiving a first signal which is indicative of a level of a remuneration for electrical energy, which is fed currently and/or in the future into a grid to which the wind turbine is connected, producing a control signal dependent on the first signal, and controlling the wind turbine with the control signal for generating power of the wind turbine, that is dependent on the control signal. A wind turbine and a central control for carrying out such a method and a system comprising a central control and a plurality of wind turbines.
Claims15
A method of operating a wind turbine, comprising:
- receiving a first signal indicative of a remuneration of electrical energy currently fed and/or to be fed into a grid, wherein the wind turbine is coupled to the grid;
- and
- generating a control signal based on the first signal;
- and
- controlling the wind turbine using the control signal for generating power based on the control signal, wherein controlling the wind turbine includes:
- storing a schedule specifying a plurality of different operating points of the wind turbine for a plurality of different time periods, respectively, the plurality of different time periods being in a pre-defined period of time, and each operating point of the plurality of different operating points representing a setting of the wind turbine that is dependent on wind speed;
- and
- operating the wind turbine per the plurality of different operating points specified by the schedule,
- wherein an operating point of the wind turbine changes in response to the first signal changing by more than a pre-defined second threshold value, and the operating point of the wind turbine does not change in response to the first signal changing by less than the pre-defined second threshold value.

A wind turbine, comprising:
- a controller configure to:
- generate or receive a control signal dependent on a first signal, the first signal being indicative of a remuneration for electrical energy currently fed and/or to be fed into a grid, wherein the wind turbine is coupled to the grid, wherein:
- the wind turbine is configured to generate a power output based on the control signal,
- a schedule specifying a plurality of different operating points of the wind turbine for a plurality of different time periods, respectively, is stored, and
- the plurality of different time periods are in a pre-defined period of time, and each operating point of the plurality of different operating points represents a setting of the wind turbine that is dependent on wind speed;
- and
- operate the wind turbine per the plurality of different operating points specified by the schedule,
- wherein an operating point of the wind turbine changes in response to the first signal changing by more than a pre-defined second threshold value, and the operating point of the wind turbine does not change in response to the first signal changing by less than the pre-defined second threshold value.
