The flywheel, made of durable materials like composite carbon fiber, stores energy in the form of rotational kinetic energy. Here’s a breakdown of the process: Energy Absorption: When there’s surplus electricity, such as when the grid is overproducing energy, the system uses that excess power to accelerate the flywheel.
Flywheel systems have several advantages, particularly in applications requiring fast charge and discharge cycles. Rapid Charge/Discharge: Flywheels can charge and discharge electricity much faster than traditional batteries, making them ideal for balancing power grids or managing short-term fluctuations in energy demand.
The flywheel can be used to smooth out the discontinuous energy source . FESS is generally supported by active magnetic bearing (AMB) systems due to their low friction Flywheels have been used traditionally to smoothen out fluctuations in irregular drive mechanics.
The following equations describe the energy capacity of a flywheel: (2) E m = α ′ α ′ ′ α ′ ′ ′ K σ / ρ (3) E v = α ′ α ′ ′ α ′ ′ ′ K σ where α ′ is the safety factor, α ′ ′ the depth of discharge factor, α ′ ′ ′ the ratio of rotating mass to the total system mass, σ the material’s tensile strength, K the shape factor, and ρ the density.
