This is of course a very broad classification of tools that is only supposed to illustrate the focus of pandapower without considering the diverse landscape of existing tools. A more detailed analysis of existing open source tools and the gap that pandapower closes can be found in . Overviews over existing open source tools can also be found in or .

The combination of the internal power system with the facility loads makes every system unique. What happens when all your lights are nice and bright and suddenly, they flicker throughout your facility? When your motor abnormally heats or is replaced multiple times due to heat? The voltage of your facility sags or swells for a short time then returns back to normal?
