Thanks to the unique advantages such as long life cycles, high power density, minimal environmental impact, and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently.
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.
Almost all the existing flywheel systems are designed for specific applications such as frequency regulation or UPS. They require specialized knowledge and techniques for manufacture, assembly, and maintenance, which prevents them from being produced in large quantities to reduce cost per unit.
