Abstract:

Energy storage is a key supporting technology for solving the problem of large-scale grid connection of renewable energy generation, promoting the development of new energy vehicles, and achieving the medium-and long-term goals of carbon peak and carbon neutralization. The hybrid energy storage system composed of an energy-type energy storage device and a power-type energy storage device is an efficient system for energy and power management that gives full play to the durability of the energy-type energy storage and the rapidity of the power-type energy storage. It also greatly improves the comprehensive performance and economy of the energy storage system. This paper summarizes the energy and power electrochemical energy storage technologies, and characteristics and various battery-supercapacitor hybrid energy storage systems (BSHESS). The application of the hybrid energy storage system in the power grid energy storage, new energy vehicles, rail transit, and other fields is analyzed. The key technologies of the BSHESS, including their control and energy management, are analyzed in detail, and the control methods commonly used in the hybrid energy storage system are summarized. Moreover, an analysis of the parameter matching and technical economy of the BSHESS is performed. The topological structure classification of the BSHESS is summarized, and the advantages and disadvantages of each topological structure are discussed. In addition, a simulation comparison between the BSHESS and the single energy storage system is performed to verify the superiority of the former over the latter. Finally, development prospects are proposed.
