For a typical network the AC load flow approach converges at an average of ca. 2.5 iterations. For a 6’000 mode, 9’000 branch UCTE network the iterative solution process for the base case takes about 70 milliseconds on a notebook running on Windows XP. The total computing time for a list of ca 2000 cases in the same network is ca. 35 seconds. The swiss contingency list (about 300 entries), embedded into the entire UCTE network is calculated in 3.5 seconds.
