Magnetic levitation flywheel energy storage, known for its high efficiency and eco-friendliness, offers advantages such as fast response times, high energy density and long lifespan, presenting significant potential for use in power systems.
The working principle of flywheel energy storage: under the condition of surplus power, the flywheel is driven by electric energy to rotate at a high speed, and the electric energy is converted into mechanical energy for storage; when the system needs it, the flywheel decelerates, and the motor operates as a generator to convert the kinetic energy of the flywheel into electric energy for the user use.
A typical system consists of a flywheel supported by connected to a . The flywheel and sometimes motor–generator may be enclosed in a to reduce friction and energy loss. First-generation flywheel energy-storage systems use a large flywheel rotating on mechanical bearings. Newer systems use composite Through the “perfect combination” of flywheel and lithium battery energy storage, it combines the advantages of flywheel energy storage with large instantaneous power, millisecond response, multiple charge and discharge times, lithium battery energy storage capacity and high frequency modulation range, and cooperates with thermal power units to assist frequency modulation.
