As the basis of wind power dispatch and operation, wind power forecasting plays an important role in improving the wind power accommodation level in China. Taking short-term wind power forecasting as the research object and focusing on the main technologies involved in the short-term wind power forecasting, the research history at home and abroad is sorted out, and the advantages of short-term power forecasting technologies at home and abroad are compared. On this basis, the construction of wind power forecasting systems in China and the forecasting errors in practical applications are introduced. The characteristics of errors are analyzed from the three dimensions of time, space and probability distribution. The causes of the errors are analyzed from the input data and the power prediction model, and the common problems facing the world and the special problems facing China are summarized. Finally, from an application point of view, relevant suggestions are given to improve the accuracy of short-term wind power forecasting strategies in China.
