Very "flywheel-like" solutions, however, spin at higher speeds and incur more flywheel energy loss, requiring more total energy storage to compensate. The optimal solution in the laboratory scale results was the one that required the minimal stored energy to complete the vehicle drive cycle, the lowest E d [ 58, 64 ].

In the context of the multi-phase machine-based Flywheel Energy Storage System with isolated neutrals, each set of three-phase windings operates through a three-phase voltage source inverter (VSI). Three main configurations can be employed to integrate the n number of DC capacitor links out of the machine-side n VSIs in microgrids, allowing them to be
A flywheel-storage power system uses a flywheel for energy storage, (see Flywheel energy storage) and can be a comparatively small storage facility with a peak power of up to 20 MW. It typically is used to stabilize to some degree power grids, to help them stay on the grid frequency, and to serve as a short-term compensation storage.
Energy storage systems (ESS) provide a means for improving the efficiency of electrical systems when there are imbalances between supply and demand.
