Vaal University of Technology, Vanderbijlpark, Sou th Africa. Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.
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.
A dynamic model of an FESS was presented using flywheel technology to improve the storage capacity of the active power distribution system . To effectively manage the energy stored in a small-capacity FESS, a monitoring unit and short-term advanced wind speed prediction were used . 3.2. High-Quality Uninterruptible Power Supply
However, the high cost of purchase and maintenance of solar batteries has been a major hindrance. Flywheel energy storage systems are suitable and economical when frequent charge and discharge cycles are required. Furthermore, flywheel batteries have high power density and a low environmental footprint.
In Stephentown, New York, Beacon Power operates in a flywheel storage power plant with 200 flywheels of 25 kWh capacity and 100 kW of power. Ganged together this gives 5 MWh capacity and 20 MW of power. The units operate at a peak speed at 15,000 rpm. The rotor flywheel consists of wound CFRP fibers which are filled with resin. The installation is intended primarily for frequency c
Large synchronous flywheels are also used for energy storage, yet not to be mistaken with FESS. They use very large flywheels with a mass in the order of 100 tonnes.
In the renewable energy sector, flywheel systems are increasingly integrated into wind and solar power systems
An accelerating torque causes a flywheel to speed up and store energy, while a decelerating torque causes a flywheel to slow down and regenerate energy. The earliest
