I did not find any resource in this forums searching this keyword. How can I find (or make) an ECDI file?

Thanks in advance.

The ECDI file is the economic dispatch data file. You can find more information on the formatting of this file in section 5.31 of the program operation manual (POM). For the full version of PSSE 34, the POM is located at C:\Program Files (x86)\PTI\PSSE34\DOCS, although it might be slightly different for Xplore. You can also navigate to the POM through the PSSE GUI with Help > PSSE Documentation.

Thanks a lot. I've found it in POM Article 5.32.

In PSSE Xplore 34 version, I've found that there is an example .ECD file given in the 'EXAMPLE'' folder (C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE) named savnw.ecd. To import this into PSSE, I used the following code snippet:

# opening .SAV file first
psspy.case(r"""C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE\savnw.sav""") 

# solving for load flow
psspy.fnsl([0,0,0,1,1,1,0,0]) 

# importing and running ECd for particular load (3285.6 MW) and MVA (100 MVA)
psspy.ecdi(0,1,1,r"""C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE\savnw.ecd""",0,[0.0,0.0])
psspy.ecdi(0,1,2,r"""C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE\savnw.ecd""",0,[0.0,0.0])
psspy.ecdi(0,1,3,r"""C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE\savnw.ecd""",0,[ 3258.6, 100.0])
psspy.ecdi(0,1,4,r"""C:\Program Files (x86)\PTI\PSSEXplore34\EXAMPLE\savnw.ecd""",0,[0.0,0.0])
