Grey prediction model of power load based on exponential smoothing improvement [PDF]

open access: yesAIP Conference Proceedings, 2017
Grey system theory has the advantages of needing little sample data and calculating no characteristic quantity; it is widely applied in power load prediction; but it has certain limitation the larger the data discretization degree is, the larger the gray scale is and the larger the influence on prediction precision is.
