Abstract: With the increasing penetration rate of new energy in the power generation system, the uncertainty of its output brings great challenges to the stable operation of the power system. It is imperative to build an efficient and reliable energy storage system. Hybrid energy storage can satisfy the task of wave calming under the demand of multiple scenarios. This paper focuses on the hybrid energy storage system composed of a supercapacitor and lithium battery, mainly introduces its characteristics and topology, and discusses the key role in calming new energy fluctuations and peak cutting and valley filling. The internal power distribution strategy of hybrid energy storage is sorted out, and it is clear that the optimization goal should balance economy and reliability, and there should be corresponding optimization goals in different scenarios. It points out that a variety of topologies should be built in the future, and calls for the active application of new wide-band gap materials and multi-sided collaborative configuration combined with intelligent optimization algorithms to promote the more efficient and stable application of hybrid energy storage systems in the new power system.
