Flywheel energy storage system is a technology that uses rotational inertia to store and release energy. It consists of a rotating flywheel and a motor/generator connected to it. When the system needs energy storage, the motor converts electrical energy into mechanical energy and accelerates the rotation of the flywheel. When energy needs to be released, the flywheel drives a motor that converts the machine into electricity.
The flywheel energy storage system has the advantages of fast response, high efficiency and long life, and is suitable for occasions requiring instantaneous high energy output, such as power grid frequency regulation and electric vehicle power compensation. At the same time, it can also be combined with other energy storage technologies, such as battery energy storage systems, to form a hybrid energy storage system to meet different energy needs and application scenarios.
