Issue
Hello! I have a huge network that contains only switches, transformers, lines, buses, loads, and one external grid. We run AC powerflow on it with runpp(), which succesfully converges. However, DC powerflow rundcpp() returns NaN results for all components. Our assumptions that the problem is somehow with a lot of switches in the network. We removed switches by converting network to PPC and then back to pandapower network. After that the DC powerflow gives valid results.
What could be the issue there? What parameters of switches should we be aware off ? Or is it problem due to a lot of switches in the network? Has anyone here encountered problem like that?
We found out what the problem was. Transformers parameters shifting_degree was NaN. When we set it to 0, DC powerflow gave results. It is strange though, that AC powerflow was not affected by it.
