In view of the nonlinear and non-stationary characteristics of wind power time series, this paper presents a modified ensemble empirical mode decomposition(MEEMD)-sample entropy(SE)-ARMA wind power ultra short term combined forecasting model. The white noise signal added in the EEMD decomposition is changed to two groups positive and negative white noise signal which have the equal absolute value, and the EMD steps of the decomposition process of MEEMD is improved with the endpoint extension and three piece...
