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).
