For the flywheel model, the behaviour is derived from the Amber Kinetics Model 32 (Amber Kinetics, 2018). The following equation is used for modelling flywheel operation for microgrid applications (Blechinger, 2015), which is an idealized energy storage equation:
These flywheel batteries, unlike chemical batteries, have a long life, a high-power density to weight ratio, and a small footprint. As an energy storage medium, these systems are used with UPS. These are typically used in situations where a large amount of energy is required in a limited amount of time.
7. Controlling a flywheel is much simpler than managing a battery. The reason is that batteries, unlike flywheels, have memory & change their characteristics with time, temperature, number of cycles & past charge/discharge history. 8. Unlike batteries, steel flywheels are heavy & are not practical for vehicles. 9.
Indeed, the development of high strength, low-density carbon fiber composites (CFCs) in the 1970s generated renewed interest in flywheel energy storage. Based on design strengths typically used in commercial flywheels, s. max/r is around 600 kNm/kg for CFC, whereas for wrought flywheel steels, it is around 75 kNm/kg.
