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).
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.
p [ W kg] must also be regarded. When it comes to a Flywheel Energy Storage System (FESS), the stored kinetic energy is proportional to flywheel mass moment of inertia and the square of flywheel rotational speed. For a modern high-speed FESS, the energy is sought to be increased by maximising rotational speed rather than flywheel size and mass.
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.
