Transfer limit of a transmission tie
Hi there,
For a dynamic simulation, is there a way to establish the transfer limit of a transmission tie? For example, active power being transferred through a branch should not exceed 200 MW.
Cheers

What are you looking for, something to flag that the limit has exceeded 200 MW? Or something to curtail gen / load to limit the transfer? You could build a misc. user model to achieve those, but it will require a bit of FORTRAN.
What you are actually doing is trying to establish the stability limit of the transmission tie. Perform an iterative dynamic simulation where you increase the transfer across a tie from one area to another. Record the power transfer in MW where instability first occurs.
Thanks for your support. I want to curtail active power coming from a transmission line. So, do I need a misc user model to achieve this?
If you want to control the flow along the transmission line, you may want to install a phase-angle/phase-shifting transformer.
Yes a misc user model could do it, but the question is *how* do you want to curtail it? As ffl pointed out, a PST would do the trick, but that isn't the only way.
