How does a flywheel energy storage system work?
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 produce electricity.
How does a vertical flywheel energy storage system affect power?
This will reduce motor power and affect the normal operation of the system. For vertical flywheel energy storage systems, most of the exergy loss in the heat transfer process is concentrated in the motor stator, casing, and cooling water. As the power increases, the proportion of exergy loss in the stator decreases.
What are the types of loss in flywheel energy storage system?
Various types of loss in flywheel energy storage system. The main loss of the system is that of the motor, most of which is transformed into thermal energy, leading to an excessively high motor temperature [20, 22, 24].
What is a flywheel energy storage system (fess)?
As shown in Fig. 1, a typical flywheel energy storage system (FESS) consists of a flywheel, motor/generator (hereinafter referred to as the “motor”), bearings, sealed chamber, inverter, and auxiliary equipment such as vacuum and cooling devices.
