Apart from the flywheel additional power electronics is required to control the power in- and output, speed, frequency etc. Fig. 1. Basic layout of a flywheel energy storage system . The kinetic energy stored in a flywheel is proportional to the mass and to the square of its rotational speed according to Eq. (1).
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.
Moreover, flywheel energy storage system array (FESA) is a potential and promising alternative to other forms of ESS in power system applications for improving power system efficiency, stability and security . However, control systems of PV-FESS, WT-FESS and FESA are crucial to guarantee the FESS performance.
In Ontario, Canada, Temporal Power Ltd. has operated a flywheel storage power plant since 2014. It consists of 10 flywheels made of steel. Each flywheel weighs four tons and is 2.5 meters high. The maximum rotational speed is 11,500 rpm. The maximum power is 2 MW. The system is used for frequency regulation.
Throughout the process of reviewing the existing FESS applications and integration in the power system, the current research status shows that flywheel energy storage systems have the potential to provide fast and reliable frequency regulation services, which are crucial for maintaining grid stability and ensuring power quality.
Field applications of FESS and flywheel-HESS on wind power plants and coal-fired thermal power units, flywheel arrays connected to thermal power plant are reviewed and conducted as deregulated power system are on a trial basis and will be developed and explored for future power systems.
