Flywheel energy storage capacity configuration

What is flywheel energy storage?

The flywheel energy storage is utilized to smooth the high-frequency components of wind power obtained through EMD decomposition. For the decomposed low-frequency wind power, it is extrapolated to an hourly timescale for subsequent two-stage robust optimization in the data center.

How much power does a G3 flywheel store?

GRC has completed a detailed design of the G3 flywheel module which stores 2100 W-hr at 100% DOD and has a power rating of 3300W at 75% DOD. A sizing code has been designed which can be used to estimate the mass of a G3 type design as a function of energy stored and power. The flywheel system will interface with the existing mounting hardware.

How can a high-frequency flywheel energy storage device transform wind power?

Second, we employ the EMD technique to configure a high-frequency flywheel energy storage device, realizing the wind power transformation from large fluctuations to small fluctuations and the convergence of the wind power fluctuation curves in minute- and hour levels.

Can flywheel energy storage mitigate high-frequency fluctuations?

On the basis of the wind power curve being decomposed and reconstructed with high and low frequencies using formulas (1 – 5) by EMD, the results of configuring flywheel energy storage to mitigate high-frequency fluctuations using formula (6) are as follows:

How many flywheel modules should a solar system have?

A low voltage motor charges the flywheel from the solar array and a separate high voltage motor provides power to the lunar base. Since reliability is achieved at the component level within a flywheel module, a system with 100 flywheel modules would provide tremendous redundancy.

What is the amplitude of a flywheel energy storage curve?

The curve has a stable and coherent amplitude within a fluctuation range of 20% and a fluctuation conservatism of 50%. The variation in the state of charge (SOC) of the flywheel energy storage is illustrated in Fig. 9.
