I know you can extract the admittance matrix from PSSE and also the voltages through python in PSSE. But could anyone tell me how can i calculate the Jacobian using these in python. I have never used python I am new to it. But i Hope i am able to learn it ast

I am unaware of any direct way to do this in PSSE.

I would look at the source code for PyPower (http://www.pypower.org) -- specifically newtonpf.py and dSbus_dV.py -- for references on how you can evaluate the Jacobian given V and Ybus in python.

That is a good tip. PSSE doesn't export or expose the Jacobian like some other simulation packages. If you write something that does calculate the Jacobian I would love to see it.

alright I am goin to try that. thanks a lot

@Amrit why do you need to calculate the Jacobian if you are already using PSSE?

Interested to know if anyone has success on this? Load flow Jacobian can always provide additional insight, e.g. modal analysis etc.

What is the API for extracting the admittance matrix?
