CANBERRA FLYWHEEL ENERGY STORAGE

Flywheel composite energy storage

Flywheel energy storage is a mechanical energy storage technology with high power, fast response, high frequency and long life, which is suitable for transportation (rail transit [5–7], ship [8,9], automobile [10–13], aviation [14,15]), power grid quality management [16–19], wind power generation [20–22], and potential energy recovery of drilling rig [23].

Wind flywheel energy storage

Hybrid energy storage, with its high power density, energy density, and long lifespan, has become a crucial support for grid-connected wind power systems. 5 Energy-based storage (e.g., batteries and hydrogen) is effective for smoothing long-term power fluctuations, while power-based storage (e.g., supercapacitors and flywheels) responds quickly to transient fluctuations.

There are several ways to cool flywheel energy storage

Feasible solutions for rotor heat dissipation in flywheel energy storage systems mainly include: filling low-temperature inert gases to enhance rotor convective heat exchange without significantly increasing low-speed flywheel friction losses; designing low-loss motors, typically using multi-phase winding designs to eliminate high-frequency shockwaves, thereby reducing rotor eddy current losses; and considering the feasibility of cooling structures based on existing research in vacuum oil cooling.
