Abstract

The invention discloses a wind power distribution method, device and system and a readable storage medium. The method comprises the steps of carrying out the adaptive segmentation of an original wind power signal based on a Fourier transform algorithm, segmenting the original wind power signal into a plurality of continuous intervals, and constructing an empirical scale function and an empirical wavelet function on the segmented intervals, determining a detail coefficient and an approximation coefficient based on the empirical scale function and the empirical wavelet function, determining a modal component according to the detail coefficient and the approximation coefficient to obtain grid-connected power, low-frequency power and relatively high-frequency powe, and distributing the low and medium frequency power to the storage battery, and distributing the high frequency power to the super capacitor. The method can avoid the defects that the method is sensitive to the volatility of renewable energy sources, wavelet bases are difficult to select in wavelet decomposition, and empirical mode decomposition lacks mathematical theories and is difficult to model.

Description

technical field [0001] The invention belongs to the technical field of hybrid energy storage, and in particular relates to a wind power distribution method, device, system and readable storage medium. Background technique [0002] In recent years, with the rapid growth of energy demand and the increasingly prominent environmental problems, new energy sources have received extensive attention. Among them, wind power generation has been rapidly developed in the world, but the fluctuation and intermittent characteristics of wind energy greatly limit the development and utilization of wind power, which promotes the rapid development of energy storage systems. The hybrid energy storage system can achieve the purpose of peak shaving and valley filling to stabilize power fluctuations, so that the system can operate more safely and stably. Battery technology is relatively mature and has the characteristics of high energy density. As a power type energy storage element, supercapacit...
