Flywheel energy storage motor speed regulation

Dynamic characteristics analysis of energy storage flywheel motor

The flywheel energy storage system (FESS) converts the electric energy into kinetic energy when the speed is increased by the two-way motor and the opposite when reduced. The energy storage capacity depends on the inertia and maximum speed of the rotor. [10, 11], charge and discharge control methods and strategies, and applications in power

Broadly speaking, the flywheel spinning speed ω allows classifying FESSs in two types [7]: low-speed FESSs (< 6000 rpm) and high-speed FESSs (10 4 –10 5 rpm). In order to maximize the energy efficiency low-speed FESSs make use of conventional technologies, whereas high-speed FESSs make use of advanced technologies.

Flywheel Technology

A flywheel is an energy storage device that is capable of storing kinetic energy in a spinning mass [37]. It operates by drawing electrical energy from the primary source and stores it in high density rotating flywheel and is basically of two types: the low speed flywheel (up to 6000 r/min) and high speed flywheel (up to 60,000 r/min).

Technology: Flywheel Energy Storage

Power-to-power Summary of the storage process Flywheel Energy Storage Systems (FESS) rely on a mechanical working principle: An electric motor is used to spin a rotor of high inertia up to 20,000-50,000 rpm. Electrical energy is thus converted to kinetic energy for storage. For discharging, the motor acts as a generator, braking the rotor to
