Flywheel storage power system is a type of energy storage system that uses kinetic energy to store electricity. It works by using a large, spinning flywheel connected to a motor and generator. The flywheel is spun up to a high speed by the motor and the energy generated by the motor is then stored in the flywheel. When energy is required, the generator is used to extract energy from the flywheel and convert it back into electrical energy. Flywheel storage power systems are considered to be a reliable and efficient form of energy storage, as they can store and supply large amounts of energy quickly.
