Molten salt energy storage exhibits several advantages

including high energy density

excellent thermal stability

and prolonged heat retention duration.This paper summarizes the types of molten salt energy storage and its key technological processes.The basic structure of integrating molten salt storage into microgrids is proposed.The operational process of the molten salt storage system is analyzed in detail.A case study of an energy storage station located in northwestern China is presented

focusing on the composition and thermal properties of the molten salt

the capacity of thermal storage tanks

the electrical-to-thermal conversion apparatus

and the molten salt transportation system within the microgrid configuration.The findings offer technical guidance for the deployment of molten salt energy storage in microgrid applications.
