It only means that it did not converge in the default number of
iterations. It may be that the problem is infeasible. You can try
increasing the number of iterations via ...
opt = mpoption('VERBOSE', 2, 'CONSTR_MAX_IT', 250);
runopf('yourcase', opt);
Also, when creating a new case, it is always a good idea to make sure
that you can successfully solve a power flow, before attempting an
OPF, but without more information it is impossible to know what is
happening in your case.

Dear Sir,
Thanks for your response to my earlier querry.
I have been facing a problem that when I tried to run a separate OPF
program for a case of 6 buses, using 'fmincon' , a message is
displayed on command window as follows:
Maximum number of function evaluations exceeded;
increase OPTIONS.MaxFunEvals.
Please help me that where I am wrong.
