Hi,
I am trying to reduce the size of IEEE 14 bus system by 100 in order to
use/analyse the system to be used with small generating units. Due to the
smaller size of additional generators I am considering, it will be easy if the
size of the system can be reduced by 100 (i.e. reducing the size of existing
generators and loads by 100). I used the following codes, but error message
comes when I try to run the opf (Matrix is close to singular or badly scaled,
numerically failed etc..)
mpc = loadcase('case14');
mpc.gen (:, 2:5) = mpc.gen(:, 2:5) / 100; % dividing PG, QG, QMAX & QMIN by 100.
mpc.gen (:, 9) = mpc.gen (:, 2)/100 + 100; % Reducing the PMAX
mpc.bus (:, 3:4) = mpc.bus (:, 3:4) / 100; % diving PD & QD by 100
mpc = ext2int(mpc);
savecase('case14_new’, mpc);
runopf ('case14_new’);
I am not sure, whether the size of the system can be reduced by 100 in this
case.
Can anybody pls help me in this regard.
