How can I change the initial battery charge of the example microgrid in Matlab?

Hello, I'm working with the example microgrid that comes with Matlab/Simulink as shown here:

https://www.mathworks.com/help/physmod/sps/examples/simplified-model-of-a-small-scale-micro-grid.html

It can be accessed by typing in 'power_microgrid' in the terminal.

The battery charge is initialized to 80%.

How can I change this value to something else, say 90%?

If you right click on the Battery_Simple_Dynamics subsystem, you can go to Mask -> Look Under Mask. Here, you will see that the state of charge is being computed in this subsystem. The AH*0.2*3600 constant block after changing to AH*0.1*3600 I then see an initial charge state of 90%.

Yes, that works, thank you!

Right click, Mask, Look under Mask

Find the Constant block showing "AH*0.2*3600". "0.2" is the determing value. Change it to be 0.1 to make the initial SOC as 90%.
