Flywheel energy storage systems (FESSs) store kinetic energy in the form of Jω 2 ⁄2, where J is the moment of inertia and ω is the angular frequency. Although conventional FESSs vary ω to charge and discharge the stored energy, in this study a fixed-speed FESS, in which J is changed actively while maintaining ω, was demonstrated.A
Interconnection rules dictate how efficient and costly it is to install a grid-connected clean energy system. If the process is slow, expensive, and/or unpredictable, it can impede investment and prevent a more rapid shift to clean energy. Energy storage is critical to the transition to a 100% clean energy future, but storage faces unique
