Abstract
A method for compensating at least partially a frequency deviation in a grid is provided in which a grid frequency is determined and the grid frequency is applied to a grid frequency criterion. If the grid frequency meets the grid frequency criterion, a determination is made as to a set of wind turbines from a wind turbine power plant fleet based on the grid frequency criterion, and a command for a transient frequency response is transmitted to the set of wind turbines.
Claims15
A method for compensating at least partially a frequency deviation in a grid, the method comprising:
- determining a grid frequency,
- applying the grid frequency to a grid frequency criterion,
- in case the grid frequency meets the grid frequency criterion,
- determining a set of wind turbines from a wind turbine power plant fleet based on the grid frequency criterion, and
- transmitting a command for a transient frequency response to the set of wind turbines.
A grid operating device for compensating a frequency deviation in a grid, the grid operating device comprising:
- a grid frequency determination unit for determining a grid frequency,
- a grid frequency comparison unit for comparing, if the grid frequency meets a grid frequency criterion,
- a wind turbines determination unit for determining a set of wind turbines from a wind turbine power plant fleet based on the met grid frequency criterion, and
- a transient frequency response command transmission unit for transmitting a command for a transient frequency response to the set of wind turbines.
