The invention discloses an annular vacuum pipeline magnetic suspension high-speed train energy storage system, relates to the field of energy storage, and is mainly used for energy storage to solve the problems of renewable energy consumption and power grid peak regulation. The system is composed of a linear motor, an annular vacuum pipeline, a magnetic suspension device, an annular high-speed train, a vacuum pump, a bidirectional converter and the like. According to the system, the annular high-speed train running in the annular vacuum pipeline in a magnetic suspension mode serves as main energy storage equipment, friction resistance loss is effectively reduced, and energy loss in the energy storage process is reduced. In the charging process of the system, a linear motor drives an annular high-speed train to accelerate, and electric energy is converted into kinetic energy of the annular high-speed train to be stored; in the discharging process, the annular high-speed train drives the linear motor to generate electricity and decelerate, and kinetic energy of the train is converted into electric energy to be output. The system is high in charging and discharging efficiency, can achieve ultra-large-capacity storage of electric energy, and is of great significance in improving the utilization rate of renewable energy sources and improving the peak regulation capacity of a power grid.
