While many papers compare different ESS technologies, only a few research, studies design and control flywheel-based hybrid energy storage systems. Recently, Zhang et al. present a hybrid energy storage system based on compressed air energy storage and FESS.
Electric energy is stored in the flywheel rotor as kinetic energy. The shape and material of the flywheel directly affect the amount of energy that can be stored. The stored energy is directly proportional to the square of the angular velocity and the moment of inertia of the flywheel. When the flywheel rotates, the kinetic energy is expressed as
