Thanks to the unique advantages such as long life cycles, high power density and quality, and minimal environmental impact, the flywheel/kinetic energy storage system (FESS) is gaining steam recently.
Flywheel energy storage systems (FESSs) may reduce future power grid charges by providing peak shaving services, though, are characterized by significant standby energy losses. On this account, this study evaluates the economic- and technical suitability of FESSs for supplying three high-power charging electric vehicle use cases.
The flywheel schematic shown in Fig. 11.1 can be considered as a system in which the flywheel rotor, defining storage, and the motor generator, defining power, are effectively separate machines that can be designed accordingly and matched to the application. This is not unlike pumped hydro or compressed air storage whereas for electrochemical …
