Flywheel energy storage systems in hybrid and distributed electricity generation

In this article, we will demonstrate the benefit of the electromechanical storage of energy over long operating cycles (with time constants ranging from several minutes to a few hours), within the scope of decentralized electrical energy production. Both the principle and technology of the primary components used in an electromechanical accumulator will be presented herein. A number of well-known examples of systems will be shown in order to derive a summary state-of-the-art. We will then proceed by providing the example of a prototype developed at the SATIE Laboratory in the aim of designing a stationary accumulator for a domestic application requiring power on the order of one kilowatt.
