📥 Importing PSS/E Models into HYPERSIM

Step-by-Step
Create a new HYPERSIM model

File → New → choose folder, name it, click Save

Open the Network Import tool

Network ribbon section → Network Import

Select PSS/E as source format

Provide the .raw file path

Browse to your PSS/E *.raw file

:warning: For dynamic data: your *.dyr file must have the exact same name as the *.raw file and be in the same directory — HYPERSIM will auto-detect it

:cross_mark: You cannot import a .dyr file alone without a .raw file

Configure import options (optional)

Replace machines by sources — substitutes all machines with ideal voltage sources

Group machines with controls — merges machines + controllers into a subcircuit

Click Import and wait for confirmation

Review reports & run network analysis

Check the generated logs for ignored/unsupported components

Use the Analyze button (Network section) to catch errors — e.g., replace parallel CP transmission lines with PI lines if decoupling errors occur
