Analysis of the Moment Inertia of Energy Storage System

In power system, the moment of inertia is the main index to measure the frequency change rate of power grid. The bidirectional power control of energy storage system improves the frequency modulation capability of power grid, which means that the energy storage system provides additional moment inertia for power grid.

4.2: Newton''s First Law of Motion

The property of a body to remain at rest or to remain in motion with constant velocity is called inertia. Newton''s first law is often called the law of inertia. As we know from experience, some objects have more inertia than others. It is obviously more difficult to change the motion of a large boulder than that of a basketball, for example.

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th
