1. Software version
MATLAB2013b
2. Theoretical knowledge of this algorithm
Here, reference is made to the following literature, which is the application of flywheels and batteries in microgrids:

The whole system is mainly divided into three parts, flywheel part, battery, controller. In the following, we will introduce and analyze these three parts respectively.
Flywheel part:
In this part, we mainly build the following models in simulink
(Main reference 1: http://www.doc88.com/p-387749815615.html):
(Main reference 2: http://www.docin.com/p-630527937.html):
Based on the framework in this paper, the resulting model is as follows:
Battery:
This part mainly uses the modules that come with simulink, and its main structure is as follows:
Controller:
It is mainly based on the paper on the website above, take a closer look.
Then we introduce the structural correspondence of the entire system, as can be seen from the above references:
That is to say, the structure of the flywheel energy storage system is as shown above.
That is, the battery model is connected to the flywheel model through the controller, and it is also the control operation of charging and discharging through the controller.
3. Simulation conclusion
The above is the speed of the flywheel, the first half is the charging stage, and the second half is the discharging stage. A02-23
