How can I design a flywheel energy storage on MATLAB/Simulink ?

I'm working on a new project in which I have to do a flywheel model for a simulation. Unfortunately, there isn't any all done model in the library or on this forum. I was wondering if anybody has already done it.

I would like to put this flywheel on the rotor of an asynchronous motor/generator as some turbine manufacturers do in order to benefit of a source of storage. I have looked into the asynchronous machine model and have thought of modifying the inertia of it but I don't think it will give me good results. Moreover, I have no idea of how to control the storage in this case.

Thanks in advance for your answers !

Hello Charles.

I´m working in something similar to you, and I would like to know if you have done any progress this last months.

Any help would be appreciated.

Thanks a lot for your help

Hello Charles and Ivan,

I am starting to build a flywheel model as well. Did you finish your projects with a positive outcome? Do you have Models for your flywheels you could share with me?

Thanks in advance for your help.

cheers, Piet

Hello Sir,

I started my work on the same topic but unable develop the model still. It would be great help for me if you can help me in this regard.

Hello Charles,

increasing the inertia of your rotor is a perfectly acceptable way to model the flywheel. You will then have to determine how you want to control the motor. There are numerous control methods that work for asynchronous machines. The appropriate one is highly dependent on your technical requirements and what type of system the flywheel is connected to. For instance, microgrid vs full grid changes what assumptions you can make in your control algorithm. For a microgrid, your flywheel may be large enough to actually modify the system frequency and line voltage, whereas in a grid connected sccenario, you may be able to assume constant line voltage and frequency.

As an alternative, you can create a behavioral model that does not require an actual controller. This would be done by modelling your flywheel as a rotational inertia connected to a controllable torque source. You can then control how much torque is applied to the flywheel without needing a motor controller. Simply measure speed and multiply by torque to track your power, integrate to track your energy, and you have a model that you can push and pull energy into.

Joel
