I have a two machine system consisting of a grid forming inverter and an equivalent generator representing the grid. There is an inverter step-up transformer, collector line, a main transformer and a line connecting to the equivalent generator as POI. I would appreciate if you could provide me a typical sequence for black start studies. Thank you.

What is the intention of your studies? Do you want to do power flow analysis, or analyse transients? I suspect that PSS/E is not the correct simulation tool for you to use.

That is what I'm actually thinking. The study is a requirement by the utility and should be done using PSS/E and PSCAD.

With PSS/E you will get power flow and transient stability results. When you're analysing a black start scenario, you also want to know about phenomena like transformer inrush, line and cable energization etc. For those you will need PSCAD or EMTP.

The goal of the study is to evaluate the inverter response when operating as a grid forming mode. Black start is one of the tests to evaluate its response.
