“…The few day power variation can be balanced by hydrogen based energy storage, while the short time turbulent power pulsation produced by wind turbine generator or solar thermal power system can be balanced by flywheel energy storage drive [26]. It is more suitable for repetitively absorbing and releasing electric energy for a short period of time than a battery energy storage system [27].…”

“…It is more suitable for repetitively absorbing and releasing electric energy for a short period of time than a battery energy storage system [27]. The flywheel energy storage is rediscovered nowadays for wide range of powers due to its advantages over the other energy storage systems: reliability, long-life, cost, fast response [26]. Flywheel energy storage systems operate by storing energy mechanically in a rotating flywheel.…”

“…In lowspeed flywheels, the classical technology is employed. Steel and other metallic alloys are used with traditional mechanical bearings yielding rotational speed up to 10 000 r/min and the total losses of ∼0.5%-1% of the rated power [3]. The speed limitation is caused by the bearing type and material tensile strength.…”

“…As shown in Fig. 2, the electrical side of the FESS could be integrated into the dc-link of the wind generator, or directly to the grid [3]. If the connection is across the common dc-link, the number of converters reduces to three, device losses are lesser, and the overall system efficiency is higher.…”

In a deregulated power market with increasing penetration of distributed generators and renewable sources, energy storage becomes a necessity. Renewable energy sources are characterized by a fluctuating and intermittent nature, which simply means that energy may be available when it is not needed, and vice versa. Energy storage devices can help rectify the mismatch between generation and demand at any loading condition. Such devices can also provide some ancillary services, such as frequency regulation, voltage support, power quality improvement, transmission congestion relief, and system upgrade deferral. This paper presents an overview of the flywheel as a promising energy storage element. Electrical machines used with flywheels are surveyed along with their control techniques. Loss minimization and bearing system development are introduced. In addition, power system applications of flywheels are summarized. Finally, some outstanding technical difficulties are recommended for future research work.Résumé-Dans un marché d'énergie libéralisée avec une augmentation de la pénétration des générateurs distribués et des sources renouvelables, le stockage de l'énergie est devenu une nécessité. Les sources d'énergie renouvelables sont caractérisées par leur fluctuation et leur intermittence, ce qui signifie tout que l'énergie peut être disponible quand il n'est pas nécessaire, et vice versa. Les dispositifs de stockage d'énergie peuvent aider à remédier à l'inadéquation entre la production et la demande pour toute condition de chargement. Ces dispositifs peuvent aussi fournir quelques services annexes, comme la régulation de la fréquence, la régulation de tension, l'amélioration de la qualité de l'alimentation, l'allègement de la congestion de transmission, et le report des mises à niveau. Cet article présente un aperçu du volant comme un élément de stockage d'énergie prometteur. Les machines électriques utilisées avec des volants ainsi que leurs techniques de contrôle sont examinées. La minimisation des pertes et le développement du système de palier sont introduits. En plus, les applications du système d'alimentation de volants sont présentées brièvement. Enfin, quelques défis techniques demeurent en suspens pour les futurs travaux de recherche.
