Abstract
A method for controlling at least one wind turbine, wherein the at least one wind turbine is set up to feed electrical power into an electrical power grid, and, depending on an amount of power of the electrical power grid, electrical active power is fed into the electrical power grid or electrical active power is removed from the electrical power grid and is supplied to at least one electrical consumer of the at least one wind turbine, and, depending on a further state variable of the electrical power grid, electrical reactive power is fed into the electrical power grid or electrical reactive power is removed from the electrical power grid.
Claims9
A method for controlling at least one wind turbine, the method comprising:
- configuring the at least one wind turbine to feed electrical power into an electrical power grid;
- if additional supply of the electrical power is needed in the electrical power grid, then feeding electrical active power from the at least one wind turbine into the electrical power grid;
- and
- if there is an excess supply of the electrical power in the electrical power grid, then using the at least one wind turbine to remove active power from the electrical power grid and to supply the removed active power to at least one electrical load of the at least one wind turbine;
- and
- depending on a state variable of the electrical power grid:
- feeding electrical reactive power from the at least one wind turbine into the electrical power grid;
- or
- removing the electrical reactive power from the electrical power grid, wherein the state variable includes a variable from a group of grid frequency of the electrical power grid and grid voltage of the electrical power grid.
A wind turbine comprising:
- means for configuring the wind turbine to feed electrical power into an electrical power grid;
- means for determining if an additional supply of electrical power is needed in the electrical power grid;
- means for determining if there is an excess supply of electrical power in the electrical power grid;
- means for feeding electrical active power into the electrical power grid;
- means for removing active power from the electrical power grid and supplying the removed active power to at least one electrical load of the at least one wind turbine;
- means for determining a state variable of the electrical power grid, the state variable being selected from:
- a grid frequency of the electrical power grid, and a grid voltage of the electrical power grid;
- and
- means for feeding electrical reactive power into the electrical power grid or removing electrical reactive power from the electrical power grid depending on a state of the state variable.
