High Power Density Optimal Configuration for Hybrid Energy Storage System Based on Wavelet Transform

In order to reduce the influence on the More Electric Aircraft (MEA) electric system, an optimal configuration approach of high power density in hybrid energy storage system (HESS) is proposed. According to the characteristics, the HESS is developed to minimize weight by using wavelet transform to configure HESS capacity. The concept of equivalent time (CET) is put forward, building the relationship between the load power and storage cells to select proper storage type and cell. The feasibility and validity of the proposed approach in this paper has been verified through the case study.
