The model includes: local slack bus, PV system, batteries, and DC loads.
Local slack bus uses a simplified VSC converter connected with the AC grid.
(A detailed VSC+AC grid model decreases the running speed, if you want a detail model, please contact me.)
PV system uses a standard PV model + a boost converter.
Battery uses a standard Li-ion battery model + a dual-active-bridge converter.
Demands are connected through buck converters.
The voltage on the DC bus is controlled by the grid-interconnected VSC, "Local slack bus".
You can play with the swiches on the bus, and the control in the components to see the power flow.

THANKS FOR THIS VALUABLE SIMULATION.
I have a question and I will be grateful if you lead me
how can I simulate fault on this or generally on any dc microgrid in MatLab?
I have been trying to learn more about DC microgrids for one of my power electronics courses.Is there a paperwork related to this model, since I am having trouble understanding it. If yes, can you please mail it to firstname.lastname@example.org
Thank you for the upload,
I actually need a detailed VSC+AC grid model.If so please send it to me sander,email@example.com it would help me alot!
Thanks for uploading!
Analyzing your model "DC microgrid"
and found in it a problem with the functioning of the battery:
- the charge level graph is not displayed correctly
- after three charge / discharge cycles, the battery stops functioning.
Did you encounter these problems with the model?
In the description for the model, you wrote that you can send a more detailed model, can you see it somewhere?
Sincerely, Oleg Belyi.
Thank you for the upload, I actually need a DC microgrid with a DC-link, do you have that model? if yes please email it to me at firstname.lastname@example.org
Thank you so much
Hello C. Li
Thank you for sharing this model.
Do you have any related paperwork for this model?
If so please send it to me email@example.com, it would help me alot!
Thank you for the upload, I actually need a dual active bridge connected to a battery and an a DC-link, do you have that model ? if yes please email it to me at firstname.lastname@example.org
Thank you so much
Thanks for Five Stars! I'll keep hard working and share more of my models.
