Rotor speed control of flywheel energy storage

Compared with other ways to store electricity, FES systems have long lifetimes (lasting decades with little or no maintenance; full-cycle lifetimes quoted for flywheels range from in excess of 10 , up to 10 , cycles of use), high (100–130 W·h/kg, or 360–500 kJ/kg), and large maximum power output. The (ratio of energy out per energy in) of flywheels, also known as round-trip efficiency, can be as high as 90%. Typical capacities range from 3 to 1. Flywheels can store energy kinetically in a high speed rotor and charge and discharge using an electrical motor/generator. Wheel speed is determined by simultaneously solving the bus regulation and torque equations.

Flywheel energy storage and electrical energy conversion

Flywheel energy storage (FES) works by accelerating a rotor () to a very high speed and maintaining the energy in the system as . When energy is extracted from the system, the flywheel's rotational speed is reduced as a consequence of the principle of ; adding energy to the system correspondingly results in an increase in the speed of th.

Flywheel energy storage frequency and power

In the 1950s, flywheel-powered buses, known as , were used in () and () and there is ongoing research to make flywheel systems that are smaller, lighter, cheaper and have a greater capacity. It is hoped that flywheel systems can replace conventional chemical batteries for mobile applications, such as for electric vehicles. Proposed flywh. FESSs have high energy density, durability, and can be cycled frequently without impacting performance. Therefore, the FESS is suitable for delivering high power and low energy content to the grid. These traits make it ideal for supporting short term frequency regulation in power systems.
