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.

How to control the discharge current of the battery cabinet

Use a resistive load or constant current sink to discharge a battery in a controlled manner. The choice depends on the application: a simple resistor works for basic voltage drop testing, while a current-regulated sink ensures uniform discharge across the battery’s usable range.
