How to get system base inertia
Hi, I am using the IEEE 9 bus system "IEEE9jconto20230920" provide by "jconto" in this post "Dynamic data for IEEE 9 bus".
I am aiming to get the system total inertia provide from all the generators in the system after some dynamic simulation (in pu, system base).
From document "PAGV2" I know that the inertia(H) enter in the .dry file is in pu, machine MVA base.
The inertia value in the model like GENROU is in pu, machine MVA base, in order to get the system base inertia in pu, the machine based(MVA base) which is entered in each generator and system based MVA is needed, but where could I found the system based MVA, when creating a new case we need to enter it, but after that, where can I find this value. Or is there any better option to consider?
Any suggestion will be much appreciate!
