Return to Question

I have just been started on a research project which involves finding ways to speed up the solution time of the power-flow problem (see Wikipedia here) which is basically calculating voltages at each of the buses of a given power system.

I have a few data-sets like the standard IEEE power-flow test cases, mentioned here

However, these bus-systems are still very small. Is there any database like the standard IEEE power-flow test cases mentioned above, but with a large number of buses. Large being on the order of 1000 to 10000 buses, or even larger.

If also there is some standard algorithm for generating a "fake" power system with an arbitrary number of buses, or standard technique to join say several IEEE 300 bus systems to make a larger network, that would also be helpful.
