Flywheels store rotational kinetic energy in the form of a spinning cylinder or disc, then use this stored kinetic energy to regenerate electricity at a later time. The amount of energy stored in a flywheel depends on the dimensions of the flywheel, its mass, and the rate at which it spins.
[pdf] A control algorithm developed at the NASA Glenn Research Center will allow a flywheel energy storage system to interface with the electrical bus of a space power system. The controller allows the flywheel to operate in both charge and discharge modes.
[pdf] This study proposes a group control system optimization strategy coupled with a refrigeration plant model for a primary pump variable flow system, in order to improve the automation level of the refrigeration.
