A review of flywheel energy storage systems: state of the art and
Since FESS is a highly inter-disciplinary subject, this paper gives insights such as the choice of flywheel materials, bearing technologies, and the implications for the overall
Vaal University of Technology, Vanderbijlpark, Sou th Africa. Abstract - This study gives a critical review of flywheel energy storage systems and their feasibility in various applications. Flywheel energy storage systems have gained increased popularity as a method of environmentally friendly energy storage.
The flywheel energy storage typically shares the DC bus with the grid-side converter in wind power or uninterruptible power supply systems, as illustrated in Fig. 20 [8, 82]. Fig. 20. Back-to-back plus DC-AC converter connected in DC-link. Source: Adapted from [27, 300].
l/kW—length (l) per unit power. 2.4.1. Induction Motors for Flywheel Energy Storage Systems Induction motors are often chosen for FESSs due to their simplicity, robustness, cost- effectiveness, and high-power capabilities.
and high power quality such as fast response and voltage stability, the flywheel/kinetic energy storage system (FESS) is gaining attention recently. There is noticeable progress in FESS, especially in utility, large-scale deployment for the electrical grid, and renewable energy applications. This paper gives a review of the recent
