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.
The use of new materials and compact designs will increase the specific energy and energy density to make flywheels more competitive to batteries. Other opportunities are new applications in energy harvest, hybrid energy systems, and flywheel’s secondary functionality apart from energy storage.
The flywheel as a means of energy storage has existed for thousands of years as one of the earliest mechanical energy storage systems. For example, the potter’s wheel was used as a rotatory object using the flywheel effect to maintain its energy under its own inertia .
The most common applications of flywheels in electrical energy storage are for uninterruptible power supplies (UPS) and power quality improvement [10, 11, 12]. For these applications, the electrochemical battery is highly mismatched and suffers from an insufficient cycle life, since the number of cycles per day is usually too high .
