How to get system loss from load flow

I am using "power_loadflow" function to perform load flow (LF), and I can get voltages and loads on each bus, but not total system loss. I am sure it is calculated but simply do not know where to find it (what is the variable name). As an option with "power_loadflow" function, one can generate (and save) a report, and it seems that the system loss is given at the very beginning of the report file, but I need to perform thousands of LF and therefore I need the system loss recorded automatically in a matrix or similar.

Hello Miroslav,

Are you resolved your problem?

Thanks

Hi Abde,

No, I have not. I have run the simulations without recording the loses.
