The principle of rotating mass causes energy to store in a flywheel by converting electrical energy into mechanical energy in the
The flywheel is the simplest device for mechanical battery that can charge/discharge electricity by converting it into the kinetic energy of a rotating flywheel, and vice versa. The energy storage
Flywheel energy storage (FES) Flywheel acts as a mechanical battery by storing kinetic energy in the form of rotating mass [37]. Rotor is generally mounted in evacuated cylinder, enabling it to accelerate at very fast speed utilizing renewable or off-peak electricity and storing it in form of rotational energy [37]. At the time of storing
This research suggests employing flywheel energy storage system (FESS) as an environmental energy storage system to stabilize MG frequency during the island mode of operation.

Simply put, energy storage is the ability to capture energy at one time for use at a later time. Storage devices can save energy in many forms (e.g., chemical, kinetic, or thermal) and convert them back to useful forms of energy like electricity. Although almost all current energy storage capacity is in the form of pumped hydro and the
