Hi everyone, I am wondering how

Hi everyone,

I am wondering how is it possible to simulate combined transmission system and distribution grid in one place (the global one) in any simulation tools such as Matpower or Digsilent? I want to see the effects of contingencies on transmission grid in the distribution grid measurements values. Actually, I want to attach a distribution grid to one of the load buses of the transmission grid and run the whole network. I highly welcome any suggestion.

Thanks for any help in advance

Why not, it's just another voltage level? Just add your distribution to your transmission model. Getting good modeling data will be the hard part.

Thanks. How. Can you explain it in a simulation tool which I can do it and see the effects? For example, If I want to attach a 33-bus to 14-bus ( as a load bus and run the whole network, what should I do.

In what ever modeling tool you're presently using for the transmission. The point is there's nothing special about the distribution, just add it to the transmission you're already modeling.

Thanks. Please consider that I am not a power system student. I am using Matpower and there case files for transmission grid and distribution system. As mentioned, I just want to run the whole network in one place and see the effects of contingencies on measurements values in the distribution system. If you know a better tool to do that, please let me know. Thanks

I’ve never worked with Matpower and have little familiarity with the main power flow products. But in the fault model world you’d simply copy the distribution model and paste it into the transmission model and connect as necessary while eliminating the duplicate elements.

In OneLiner it’s a piece of cake. They have a power flow option I’ve never used, but the model is the same so the process would be the same.

If that isn’t possible in Matpower perhaps something else available to you would have that capability.

Thanks. By OneLiner, you mean this website:

Yep.
