Simulation OpenEMS with my own Data (CSV File)

[DominikDHBW]

Hello,

I’m interested in integrating my own data into OpenEMS using CSV files. Could you please guide me through the process? I would like to simulate the data and view the results.

Additionally, I’m curious about where I can find the CSV files with parameters for the example PV system in the software. Could you provide some guidance on this as well?

Thank you for your help.

Best regards,

Hi,

What you could do is to use the component “Datasource CSV Direct” and paste your CSV file into the confguration. Then you can configure for example a “Simulated Production Meter Acting” and give it the datasource, and it will run through the datasouce, switching to the next value every core cycle, or after a time delta you can configure in the datasource.

The predefined CSV files you’ll find in the directory of the datasouce CSV predefined:

Of course you could also put your CSV file there and add it to the Source enum.

Best regards,
Thomas

Hi dear ,

you can read this post for more information about the ‘CSV-Source’ and CSV limitation for users who used own CSV files. it can be helpful

Using Simulator DataSource: CSV Predefined

Hello folks, I am trying to simulate my own load and PV data. [image] I defined the predefined data sources using these two files. But log output shows as below: 2023-10-22T16:33:26,505 [_cycle ] INFO [ebuglog.ControllerDebugLogImpl] [ctrlDebugLog0] _sum[State:Fault Ess SoC:50 %|L:0 W Consumption:0 W] ctrlBalancing0[State:FAULT: Running the Controller failed] ess0[SoC:50 %|L:0 W|Allowed:-10000;10000 W] meter0[UNDEFINED] meter1[UNDEFINED] modbus0[CycleDelay:987 ms] Could you please advis…

Hello,

thank you for your answer. But what would it ultimately look like in defiles or in the program? Do you have an example of this?

To speed up my simulation, I’m considering reducing the Core Cycle time to 1 ms. This would allow me to get my simulation results within a few minutes (I have 3 years data every 15 minutes, by reducing the Core cycle to 1 ms, it’s 900’000 times faster).

However, since my power measurements (Cycle core) are in Watts every 1 ms (but every 15 minutes according to my files), I’m wondering if the stored energy is representative of reality. Does it consider the 1 ms step for calculating stored energy, or is this irrelevant?
