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.

A flywheel energy storage system works by spinning a large, heavy wheel, called a flywheel at very high speeds. The energy is stored as rotational kinetic energy in the spinning wheel. When electricity is needed, the flywheel’s rotational speed is reduced, and the stored kinetic energy is converted back into electrical power using a generator.
A flywheel energy storage unit is a mechanical system designed to store and release energy efficiently. It consists of a high-momentum flywheel, precision bearings, a vacuum or low-pressure enclosure to minimize energy losses due to friction and air resistance, a motor/generator for energy conversion, and a sophisticated control system.
The amount of energy stored in a flywheel depends on the dimensions of the flywheel, its mass, and the rate at which it spins. Increasing a flywheel’s rotational speed is the most Manuscript received October 3, 2013; revised December 17, 2013.
