The operation of the electricity network has grown more complex due to the increased adoption of renewable energy resources, such as wind and solar power. Using energy storage technology can improve the stability and quality of the power grid. One such technology is flywheel energy storage systems (FESSs).
Flywheel energy storage (FES) is a very interesting technology. Fig. 9.3 shows the working principle of FES. During the off-peak hours or when the electricity production is larger than the energy demand, surplus energy is used to drive the motor connected to the flywheel. This flywheel converts the electrical energy into rotational kinetic energy.
A flywheel-storage power system uses a flywheel for energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.
The energy storage facility provided by flywheels are suitable for continuous charging and discharging options without any dependency on the age of the storage system. The important aspect to be taken note of in this regard is the ability of FES to provide inertia and frequency regulation .
Fig. 7.8 shows the integration of the flywheel energy storage system with the grid. In this method the stored energy is transferred to the grid by a generator, alternative current (AC)/direct current (DC) rectifier circuit, and DC/AC inverter circuit. Figure 7.8. Flywheel energy storage system topology.
A 10 MJ flywheel energy storage system, used to maintain high quality electric power and guarantee a reliable power supply from the distribution network, was tested in the year 2000. The FES was able to keep the voltage in the distribution network within 98–102% and had the capability of supplying 10 kW of power for 15 min . 3.5.7.
