I was trying to find the PTDF matrix in PSS/E but wasn't able to figure it out. The Dfax function calculates the OTDFbut not the PTDFs. I have tried differenct things from the manual like trying to run TLTG, SPIL. Please direct me in the appropriate direction.
Not sure what your end goal for a PTDF matrix is, but the pssarrays.sensitivityflowto_mw API calculates the flow impact of machines and loads to a specified branch.
can you be generous and explain the meaning of PTDF and OTDF? what is their purpose.
The following posting "https://www.powerworld.com/files/TrainingI11LinearAnalysis.pdf" discusses those two concepts. You can also search the net for "ptdf calculation"
thank you, can we say that the output pf PTDF is the sameas the activity TLTG inPSSE
I'm afraid you may have to make a routine your self in Python to build PTDF matrix, extracting the data from PSS/E. The PTDF is based on Ybus matrix, reactance >> resistance, so all resistance in "R" column to zero "0". Then extract Ybus from PSS/E and work with it in Python to build the PTDF matrix. There could be other parameters than affect the construction of the Ybus, take care of it. I remember you can't build the PTDF matrix directly from PSS/E but the LODF. LODF can be build directly with a command.
