Abstract：A standard power curve optimization method based on the grid method is proposed.Through grid division and data screening,abnormal data and noise interference are eliminated.The data is preprocessed in combination with the state calculation mechanism,the correction coefficient is calculated and the wind speed parameters are adjusted to optimize the standard power curve.The wind turbines in the wind farms of Gansu and Shandong are taken as examples for verification.The results show that the optimized power curve can more accurately reflect the actual power generation performance of the wind turbine under different wind speed conditions.The low wind speed range has a higher degree of conformity with the actual data,and the high wind speed range effectively reduces the deviation from the actual power output.This method significantly enhances the accuracy and reliability of the standard power curve,providing a more accurate basis for the performance evaluation and operation optimization of wind turbine units,and is conducive to improving the operational efficiency and reliability of the units.
