Using energy storage technology can improve the stability and quality of the power grid. One such technology is flywheel energy storage systems (FESSs). Compared with other energy storage systems, FESSs offer numerous advantages, including a long lifespan, exceptional efficiency, high power density, and minimal environmental impact.
FESS has been integrated with various renewable energy power generation designs. Gabriel Cimuca et al. proposed the use of flywheel energy storage systems to improve the power quality of wind power generation. The control effects of direct torque control (DTC) and flux-oriented control (FOC) were compared.
A dynamic model of an FESS was presented using flywheel technology to improve the storage capacity of the active power distribution system . To effectively manage the energy stored in a small-capacity FESS, a monitoring unit and short-term advanced wind speed prediction were used . 3.2. High-Quality Uninterruptible Power Supply
Environmental Friendliness Flywheels do not contain harmful chemicals and are generally easier to recycle, making them an environmentally responsible choice for energy storage.
Size and Weight The energy-to-weight ratio for FESSs is still generally less favorable than for some other storage options, making them less practical for mobile applications. Efficiency Advances in materials science for the flywheels have led to higher rotational speeds and thus increased efficiency in energy storage and retrieval.
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. Their advantages have become even more pronounced with advances in power electronics technology and modern motor drive sys- tems. However, there are challenges.
