Hi Chaoli,
these applications sound interesting. It is exactly the field I am also using OpenEMS for. Let me know if any questions arise and please keep me updated on your evaluation.
I assume your applications are in a scientific research environment. There are quite some universities and institutes currently working with OpenEMS (like University of Passau, Technical University of Vieanna and others.) Let me know if you need a contact.
There is also a “Simulator” currently in development, that might be interesting for your use-case. See my quick documentation in this thread: Timedata InfluxDB Question
Regards,
Stefan
