Thanks but i got just new problem..
*define_constants;*
*mpc=loadcase(case14);*
*mpc.gen(8,PV)=PQ;*
*mpc.gen(8,QG)=50;*
*rslt=runpf(mpc);*
and they are showing the following error:
Subscript indices must either be real positive integers or logicals.
Error in ext2int (line 175)
gs = ( mpc.gen(:, GEN_STATUS) > 0 & ... %% gen status
Error in runpf (line 131)
mpc = ext2int(mpc);
what is the wrong here going on ??
