A flywheel energy storage can have energy fed in the rotational mass of a flywheel, store it as kinetic energy, and release out upon demand. They work by spinning up a heavy disk or rotor to high speeds and then tapping that rotational energy to discharge high power bursts of electricity. It is difficult to use flywheels to store energy for ...

Flywheel energy storage (FES) works by accelerating a rotor (flywheel) to a very high speed and maintaining the energy in the system as rotational energy. When energy is extracted from the system, the flywheel''s rotational speed is reduced as a consequence of the principle of conservation of energy; adding energy to the system correspondingly results in an increase in the speed of th…
Pulsed power load (PPL) consumes a huge amount of energy within a very short period of time. Directly connecting a PPL to a shipboard power system (SPS) will cause large disturbance even instability during PPL deployment.
