Imagine a giant, supercharged spinning top that stores electricity like a battery— that's flywheel energy storage in a nutshell. This 21st-century "mechanical battery" uses rotational kinetic energy to store electricity, offering 90% efficiency and 20+ year lifespans [1] [8]. . Flywheel energy storage (FES) works by spinning a rotor (flywheel) and maintaining the energy in the system as rotational energy. This innovative approach harnesses kinetic energy to create a robust storage solution that addresses some major challenges faced by. . Flywheels can store grid energy up to several tens of megawatts. Kinetic energy can be described as “energy of motion,” in this case the motion of a spinning mass, called a rotor. The rotor spins in a nearly frictionless enclosure.

This chapter proposes an energy storage solution controlled by Deep Reinforcement Learning (DRL) to address fluctuating electricity costs in the smart grid (SG). . In an era where energy efficiency and sustainability are paramount, smart grid energy storage systems have emerged as a cornerstone of modern energy infrastructure. These systems are not just about storing energy; they represent a paradigm shift in how energy is managed, distributed, and consumed. The deep Q-network (DQN) method is employed to optimize the capacity configuration and operation strategy of the ESS. In this study, an isolated microgrid on a small island is selected as the research subject. It optimizes electricity trading in a variable tariff setting, yielding consumer savings averaging 20. 91% annually without altering consumption habits.
