Thanks for your reply. It does not seem to be an economical issue in Denmark with the consumed Mvarh. I will just comment on it in the report and then only discuss the MWh loss.
I am analysing a local distribution 60kV-network, with a 150/60kV tranformerstation as its feeder. When I do a load flow calculation with load profiles, over a year, I get a lot of Mvarh losses - this isn't a concept we have learned about in school. So I hope that some of you can give me an idea...
