Hello ! sorry ! I try again!
you most change type of bus
[image: image.png]
then add GEN for example
[image: image.png]
and
[image: image.png]
then save
>> mpc =loadcase('case33bw');
>> results = runpf(mpc);
befor add you have
loss Total: 0.276 0.21
generator Total: 3.92 2.44 3.72 2.30
after add
loss Total Total: 0.276 0.21:

in bus 32 change value
