With the increasing applications of power electric devices in More Electric Aircraft (MEA) power system, the electric load power in MEA displays fluctuating characteristics. The Hybrid Energy Storage System (HESS) is selected to smooth load power fluctuation. To reduce the weight of HESS, a method of optimal configuration of high power density HESS is proposed. Firstly, to build the relationship between the load power and storage cells, a concept of Equivalent Time (ET) is put forward and is used as the basis to select the energy storage system type by comparing the equivalent times. Further, the space vector is proposed:to determine the optimal cell and the cutoff frequency, the load energy is synthesized by the energy storage medium vector and the power storage medium vector, realizing the high-power density configuration of HESS. Meanwhile, the HESS capacity is calculated from the energy constraints and power constraints. Finally, the feasibility and correctness of the proposed method in this paper has been verified through the example configuration and simulation analysis.
