Introducing a novel adaptive capacity energy storage concept based on the Dual-Inertia Flywheel Energy Storage System for battery-powered Electric Vehicles and proposing a hierarchical Energy Management System/sizing framework.
The Inertia Drive technology is based on the flywheel mechanical battery concept that stores kinetic energy in the form of a rotating mass. Our innovations focus on design, assembly and manufacturing process.
That''s inertia in action – and it''s the same physics that makes inertial energy storage systems tick. This technology converts electricity into rotational energy and stores it in spinning masses like flywheels, with applications ranging from stabilizing power grids to charging electric buses faster than you can say "kinetic coffee break
Imagine thousands of spinning wheels distributed across the grid, automatically balancing supply and demand in real-time. Duke Energy''s test in Charlotte showed 12% improvement in frequency regulation accuracy compared to traditional methods.
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 inertia wheel is characterised in that the hub is made from a composite material and includes a module having a stiffness that decreases from the hub body to the rim. The invention also...
Inertia wheels are a way to store electrical energy in the form of kinetic energy. They consist of a mass rotating around an axis connected to an electric motor.

A flywheel is an inertial energy storage device that absorbs mechanical energy during periods of high energy supply and releases it during periods of high energy demand.
To solve the lack of inertia issue, this paper proposes the method of using flywheel energy storage systems (FESSs) to provide the virtual inertia and frequency support. As compared with batteries, flywheels have a much longer lifetime and higher power density.

To solve the lack of inertia issue, this paper proposes the method of using flywheel energy storage systems (FESSs) to provide the virtual inertia and frequency support. As compared with batteries, flywheels have a much longer lifetime and higher power density.
By regulating the speed of the flywheel in proportion to the grid frequency, the flywheel serves as an energy buffer that absorbs and releases its kinetic energy to provide inertia support. Furthermore, the design methods of the virtual inertia emulated by FESSs are described in detail.
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.
Our innovations focus on design, assembly and manufacturing process. Solar and wind power only produce when the wind is blowing or the sun is shining. This causes grid instability due to loss of system “inertia”, which ultimately impacts energy supply to consumers. Inertia Drive is a flywheel.
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.
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.
