Embodiment Construction
[0058] In order to describe the technical solution disclosed in the present invention in detail, the technical solution of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.
[0059] The invention provides a non-parametric probability interval ultra-short-term prediction method of wind power, which is based on an adaptive LASSO and an extreme learning machine to perform ultra-short-term prediction of wind power non-parametric probability interval. It can be applied to other ranges and fields such as load and photovoltaic output.
[0060] The prediction model flow chart of the present invention is as figure 1 Shown, its embodiment step is mainly as follows:
[0061] (1) Initialize the model parameters and import the normalized historical wind power time series;
[0062] (2) Non-linear quantile regression is used to obtain the output coefficients corresponding to the upper and lower quantiles of the confidence i...
