It depends on your application, but in general, it is fine to merge the lines
if all you care about is the aggregate behavior. The only reason I can think of
to keep them separate is if you want to look at things like the effects of
taking one of them out of service. Otherwise, the OPF and power flow solutions
should be identical with a properly aggregated line.
