Right, if you work with only one transmission topology, you can do what
Carlos says, therefore it is done automatically. If you work with many
transmission topologies, maybe you can do what I said in my previous
email. So, I was assuming you were working with many transmission
topologies.

Branch admittances are additive in the
Ybus matrix construction procedure. makeYbus uses the sparse()
function to build Ybus, and automatically adds any admittances
resulting from parallel branches in the right places. You should
have no problem with parallel li
thanks Mr. Santiago.
If I copy the row (colored row) of branch data,
Is this same:
from bus 1 to bus 4 has 2 lines and
from bus 2 to bus 6 has 3 lines ?
and is runpf calculations still valid?

You have to change (by coding) the impedances and other parameters
proportionally to the number of lines. Matpower does not that
automatically or simply working with the data file.
Hope this help.

Dear Dr Ray Zimmerman
My research is about expansion transmission planning (TEP). TEP allows a
branch has more than one line, while all cases in matpower has only single
line. I use DCPF to calculate power flow.
For example:

you will have to pass the load n generation to the case in which u want to
do pf from your main function.first make a matrix for load n geneartion n
pass it.thats how I did.

Can you provide an example of how you did 24 hour PF?
I am still not sure how, in OPF, you would include constraints that couple the
problem over time for example ramping constraints or costs...

I have done PF for 24 hours don't know about OPF. You have to feed the 24
hour load n generation variation in the form of a matrix

Hi all
I am curious if it is possible to perform OPF for a power network over time.
For example, to perform a simulation for a network in 24 hours, where we
consider one scenario each hour, i.e. 24 individual OPF. However, by including
for example ramping limits, these 24 individual OPF problem
