Our flywheel energy storage calculator allows you to calculate the capacity of an interesting type of battery!
The flywheel energy storage operating principle has many parallels with conventional battery-based energy storage. The flywheel goes through three stages during an operational cycle, like all types of energy storage systems: The flywheel speeds up: this is the charging process.
The kinetic energy stored in the flywheel is presented in Eq. (1). (1) E = 1 2 J ω 2 where E is the stored energy, J is the moment of inertia, ω is the rotational speed. The speed of the flywheel undergoes the state of charge, increasing during the energy storage stored and decreasing when discharges.
To solve the lack of inertia issue, this paper proposes the method of using flywheel energy storage systems (FESSs) to provide the virtual inertia and frequency support. As compared with batteries, flywheels have a much longer lifetime and higher power density.
Due to the advantage of flywheel, minimizing the operation times of BESS and giving priority of flywheel to respond the fluctuations is proved to be an available option to improve the life span of BESS, reduce the probability of explosion of BESS and secure operation of the hybrid energy storage system.
