Abstract：Based on the hybrid energy storage system composed of super capacitor and storage battery, the complete ensemble empirical mode decomposition with adaptive noise is used to smooth the wind power fluctuation in this paper. Firstly, according to the fluctuation of wind power, different natural mode components and allowances are obtained by the complete ensemble empirical mode decomposition. The power cut-off point k is calculated by the theory of energy entropy, and then the initial power allocation instruction is determined. Therefore, the state of charge has been constrained and optimized by the theory of fuzzy control, and the power allocation instruction of hybrid energy storage system is adjusted and modified adaptively. From the numerical example, the proposed method can adaptively realize the reasonable power distribution, and the hybrid energy storage system works in a reasonable range of charged states, which can effectively improve the system efficiency and service life.
