There is nothing special about 3-bus models, but even the standard OPF (without reserves) is infeasible on your 3-bus case. Try relaxing the voltage limits on buses 1 and 2 and relaxing the line limits until you can get runopf() to converge. Then you can gradually tighten up the constraints and see where the problems arise. Once you have a converging OPF with reasonable values, try adding the co-optimization of reserves.
