6 FAQs about [Inertial energy storage gun]

How does inertia affect energy storage?

The inertia response of an energy system limits the rate of change of frequency, known as RoCoF, when a sudden change in load is encountered . Systems such as thermal energy storage and pumped hydroelectric have very little associated inertia and may be thought of as providing slow response energy storage.

What is real inertia?

Real inertia is distinct to emulated or synthetic inertia, and may be thought of as energy storage that acts in an entirely passive manner. That is to say, the transfer of energy is determined completely by the reluctance of the system to change speed.

How much inertia is seen by the grid?

Large inertia constants may be calculated (1440 s for the developed system) and, during certain mode of operation, there is no ambiguity as to whether this inertia is “seen” by the grid. Assuming steel prices of £2000/tonne, unit energy storage costs of approximately 111.5£/kW hr are achievable with this system.

Can real inertia be used to power a synchronous generator?

The present work focuses on the preliminary development of a novel energy storage system that makes use of real inertia to address short term supply/demand imbalances while simultaneously allowing for extended depths of discharge. The concept looks to combine flywheel and compressed fluid energy stores in order to power a synchronous generator.

Does a hybrid flywheel energy storage system return “real” inertia?

Inertia must be replaced in a decarbonised grid in order to ensure stability. A hybrid flywheel energy storage system is proposed that returns “real” inertia. Active power control is possible using a differential drive unit (DDU). Case study applications and comments on turnaround efficiency are presented.

What are inertia constants?

Inertia constants may be expressed as the ratio of stored kinetic energy in a system, rotating at rated speed, to the rated electrical power of the system. Inertia constants have time units and indicate how long it would take for a rotating mass to de-accelerate to stationary if continuously discharged at rated power .
