Dear Prof. R. Zimmerman,

I'm master student working on a  project dealing with power system
optimization with additional variables  'tap ratio' and 'shift' on 9 bus
system by  *mipsopf_solver*. I have made necessary changes in respective
function files. Also I concern with only current flow constraints in
*opf_hessfcn*. For that I used command like *>>* *mpopt =
mpoption('OPF_FLOW_LIM', 2);* and* >> runopf(case9,mpopt);*. But I'm
getting errors -

Did not converge in 17 iterations.
Error using opf_args (line 315)
opf_args.m: Incorrect input parameter order, number or type

Error in opf (line 199)
[mpc, mpopt] = opf_args(varargin{:});

Error in opf (line 262)
opf(varargin)

Error in runopf (line 96)
[r, success] = opf(casedata, mpopt);

As I'm not much faliliar with MATPOWER so I could not understand what
exactly I need to rectify in *opf_args.m* file. I need your help .Thanks in
advance.


Sincerely
Mirish
