Energy storage system that converts kinetic energy

Kinetic Energy Storage Systems (KESS) are based on an electrical machine joined to a Flywheel. When the system stores energy, the electrical machine works as a motor and the flywheel is accelerated until it stores the nominal energy. When the system provides energy, the electrical machine works as a generator and the flywheel decelerates.

Energy storage systems (ESS) play an essential role in providing continuous and high-quality power. ESSs store intermittent renewable energy to create reliable micro-grids that run continuously and efficiently distribute electricity by balancing the supply and the load .

When the system stores energy, the electrical machine works as a motor and the flywheel is accelerated until it stores the nominal energy. When the system provides energy, the electrical machine works as a generator and the flywheel decelerates. KESS transform electrical energy into kinetic energy or kinetic energy into electrical energy.

Energy storage systems act as virtual power plants by quickly adding/subtracting power so that the line frequency stays constant. FESS is a promising technology in frequency regulation for many reasons. Such as it reacts almost instantly, it has a very high power to mass ratio, and it has a very long life cycle compared to Li-ion batteries.

Examples include flywheels, pumped hydro storage, and compressed air energy storage. In these systems, electrical energy is converted into kinetic or potential energy, which is then stored until required.

Energy storage systems have emerged as the paramount solution for harnessing produced energies efficiently and preserving them for subsequent usage. This chapter aims to provide readers with a comprehensive understanding of the "Introduction to Energy Storage and Conversion".
