METHOD AND APPARATUS FOR COOPERATIVE CONTROLLING WIND TURBINES OF A WIND FARM

摘要

The invention relates to a method for cooperative controlling wind turbines (10, 20) of a wind farm, wherein the wind farm comprises at least one pair of turbines (10, 20) aligned along a common axis approximately parallel to a current wind direction and consisting of an upstream turbine (10) and a downstream turbine (20). The method comprises the steps of: a) providing a data driven model trained with a machine learning method and stored in a database (51), the data driven model providing a correlation between time series data obtained from the pair of turbines (10, 20) in parallel, the time series data being aligned in time to the same wind front and a ratio of the current power production of the upstream and the downstream turbine (20) related to the aligned time series data; b) determining a decision parameter for controlling at least one of the upstream turbine (10) and the downstream turbine (20) by feeding the data driven model with the current power production of the upstream turbine (10) which returns a prediction value indicating whether the downstream turbine (20) will be affected by wake, and/or the temporal evolvement of the current power production of the upstream turbine (10) which returns a prediction of the probable development of the future power production of the downstream turbine (20); c) based on the decision parameter, determining control parameters for the upstream turbine (10) and/or the downstream turbine (20).
