Flywheel energy storage systems (FESS) are considered environmentally friendly short-term energy storage solutions due to their capacity for rapid and efficient energy storage and release, high power density, and long-term lifespan. These attributes make FESS suitable for integration into power systems in a wide range of applications.
Moreover, flywheel energy storage system array (FESA) is a potential and promising alternative to other forms of ESS in power system applications for improving power system efficiency, stability and security . However, control systems of PV-FESS, WT-FESS and FESA are crucial to guarantee the FESS performance.
Can a flywheel energy storage system control frequency regulation after micro-grid islanding?
Arani et al. present the modeling and control of an induction machine-based flywheel energy storage system for frequency regulation after micro-grid islanding. Mir et al. present a nonlinear adaptive intelligent controller for a doubly-fed-induction machine-driven FESS.
Source: Endesa, S.A.U. Another significant project is the installation of a flywheel energy storage system by Red Eléctrica de España (the transmission system operator (TSO) of Spain) in the Mácher 66 kV substation, located in the municipality of Tías on Lanzarote (Canary Islands).
