Abstract

Power fluctuation smoothing technology is crucial for the secure and stable functioning of contemporary power systems that integrate a substantial share of new energy sources. To address the problems of the over-smoothing of conventional adaptive wavelet packet techniques for wind power fluctuation smoothing and increased burden of energy storage systems, a refined adaptive wavelet packet strategy for wind power smoothing control has been developed. Initially, according to the power fluctuation characteristics of wind power in different time periods, the filter time scale is reasonably planned, and the minimum filter scale is determined to meet the system control requirements. Subsequently, the expected grid-connected power and fluctuating power are obtained by using adaptive wavelet packet decomposition filter scale. Then, a hybrid energy storage system, comprising dual batteries and supercapacitors, is employed to mitigate these power fluctuations. Finally, the advantages of the improved smoothing strategy in reducing the burden of the energy storage system are analyzed, and the operating life of the energy storage system is evaluated. Findings suggest that on the premise of ensuring the smooth fluctuation of wind power, this strategy not only reduces the burden of energy storage system, but also prolongs its operating life.
