If you need lower version of the model like Simulink 2015 or lower let me know in the comments
The description of each element is on top of it and how it was calculated. The model is flexible to work within wide range of values. If you have questions please email me at my main email: mahmoudsah@hotmail.com, student email: msaleh000@citymail.cuny,edu, gmail: mahmoudsalahem@gmail.com
In the subject of your email write: Bidirectional Mathwork question so that I would be able to track the emails even if they went to junk mail.
-------------------------------------------
I am an expert in modeling in Simulink, especially microgrids, I have encountered many problems and I was able to fix it. I used to work with dSpace and I build with my colleagues microgrid testbed at City College of New York. We modeled according to the hardware components avialable in our lab, then we build it and test it. I will try to help in case you have a question.

Amazing model, thank you for sharing it with us.

umaid ali

its a great model.......works well.......thanks a lot :)

please tell
how tuning is done for other voltage level?

Mahmoud Saleh

Sorry for the late reply i was quite busy and just saw this comment.
A quick answer on top of my head would be that the capacity of the battery is small and need to be increased, also in the past the matlab model for batteries used to give me hard time because it needs to be adjusted carefully to work porperly for your application (e.g. slow dynamics, capcity). One thing you can do, is that replace the batteries with super capacitor and increase it's size to see what will happen and understand wheater the battery model need to change or it is a control problem (i.e. the controller is slow to respond to the changes from the MG). The idea is to think about series of tests to trouble shoot where is the problem and then try to fix it.
Let me know if you have further questions and please share the outcomes of your finding so that we all learn
Best regards,
Mahmoud

By the way I am talking about voltage controller but I accidently put the comment here :D

Hi Mahmoud, I have one question: If we increase the microgrid current to 5A for example, then the voltage will rise till nearly 500V. Battery should be charging in this situation but it charges too slowly, almost it doesn't charge at all, so the voltage stays at 500V. You mentioned that (I_Microgrid + I_Bidirectional) * R_MG should be ~ V_ref which is probably why it is not working like this. But, can we adjust it so it charges the battery with bigger current and keeps the voltage at 300V at the same time? I would like to connect it to the PV panel, so when I produce too much power from the PV I will charge the battery but I will also keep the voltage at 300V...

I will converted to 2016a and upload it as soon as possible, probably during this week. However, I thought I uploaded many version of that model. Anyways, I'll double check and upload it.

i need this in 2016a
