Various Concepts on Variable Inertia Flywheel in Rotating System
Abstract. Variable inertia flywheel is an innovative approach for storing energy in a rotating system. It may replace the constant inertia flywheel effectively from the conventional rotating system. The variable inertia flywheel has less weight, and it has a great potential to adjust the moment of inertia according to the load of the system.
A series hybrid "real inertia" energy storage system
2. Series hybrid kinetic energy storage (SHyKESS) The presented hybrid energy storage system, refereed to as SHyKESS, falls into a category of systems that the authors would term "series" type systems. These are distinct to "parallel" type systems, which make up the vast majority of designs proposed in the literature.

Flywheel Energy Storage | Electric Vehicles Research
A flywheel is a rotating disk used as a storage device for kinetic energy. Flywheels resist changes in their rotational speed, which helps steady the rotation of the shaft when a fluctuating torque is exerted on it by its power source such as a piston-based engine, or when the load placed on it is intermittent. Flywheels can be used to produce ...

To alleviate air pollution and energy shortage issues, an increasing amount of renewable energy sources (RESs), such as wind power and solar photovoltaics (PVs), has been integrated into modern power systems. However, the large penetration level of renewable energies leads to the reduction of inertia as RESs are normally connected to the power …
Flywheel energy storage
A second class of distinction is the means by which energy is transmitted to and from the flywheel rotor. In a FESS, this is more commonly done by means of an electrical machine directly coupled to the flywheel rotor. This configuration, shown in Fig. 11.1, is particularly attractive due to its simplicity if electrical energy storage is needed.
