Here's what I would do. Create a matrix gen_profile with the generator output
values, where each row corresponds to a generator and each column to a week of
the year. You could set up another matrix load_profile with the nodal loads in
it, then do something like the following ...
define_constants;
mpc = loadcase('mybasecase');
for k = 1:52
mpc.bus(:, PD) = load_profile(:, k);
mpc.gen(:, PG) = gen_profile(:, k);
r = runpf(mpc);
loss(k) = sum(mpc.gen(:, PG)) - sum(mpc.bus(:, PD));
end
total_loss = sum(loss);
Hope this helps,
