Power prediction for newly added wind turbine

A system for predicting the power of a target wind turbine newly added in a wind farm, the system comprising:

• a reference wind turbine determination unit configured to determine a reference wind turbine associated with the target wind turbine;
• a power curve mapping unit configured to determine a power curve mapping relationship between the reference wind turbine and the target wind turbine according to a power curve of the reference wind turbine and a power curve of the target wind turbine;
• a power data distribution mapping unit configured to obtain the power data distribution mapping relationship between the reference wind turbine and the target wind turbine according to the wind speed historical data of the reference wind turbine and the wind speed historical data of the target wind turbine;
• and
• a wind turbine power estimation unit configured to estimate the power of the target wind turbine according to the power curve mapping relationship, the power data distribution mapping relationship, as well as the power and wind speed of the reference wind turbine.
