 ### Power Flow Analysis
-Uncomment the line in `run_egrid_agent` script where the prompt is "Run power flow analysis for case IEEE14_from_raw.gridcal" to run the power flow analysis example. Feel free to change the case name to play with various study systems. Note that you need to download the power flow cases from GridCal project repo ["Grids_and_Profiles/grids/"](https://github.com/SanPen/GridCal/tree/master/Grids_and_profiles) folder
