I assume this data is from the Baran, Wu paper [1]. A couple of comments ... 1. Setting RATE_A column to zero is actually correct for a case with no branch flow limits (see footnote 14 at the bottom of p. 49 in the latest User’s Manual). 2. In the case file you sent, all of the tie lines are in-service, operating as a meshed system, rather than the base radial configuration, and the branch impedance parameters for 5 of the branches (every other branch starting with the first) do not match exactly what’s shown in the paper. 3. I’ve attached attached a version of the case that I believe matches the data from the paper exactly. 4. Unless I’m missing something, the data given in the paper and the base case solution given in the paper are not consistent. For one thing, the voltages do not match, but even more glaring is the fact that the total load is 3715 kW, but they claim the total substation load is 5085.26 kW and that the losses are about 8%. Am I missing something? Ray [1] M. E. Baran and F. F.
