What do you mean other cases work? Are you using version 4.1? by "runse" you mean "run_se"? Do you get answer by runse('case14') without definging the measurement parameters? On Tue, Jan 10, 2012 at 4:00 PM, morteza keshavarz wrote: > Hello, > > I can't do state estimation for case118 system and

I guess the thermal limit constraint is satisfied in your case (236.55 MW). Firstly, you have to read the power flow through the line, not the injected power in one bus. Secondly, as I remember, the column rateA in the branch matrix for each case is the thermal limit of that line. In your case, the

Dear matpower community Does anybody know what is he base of voltage in IEEE 14 bus test system. I understand that it's not required to know the value of it in order to use the benchmark, but I wonder what is a reasonable assumption for the base of voltage. Regards, Arash Alimardani
