Dear Dr. Zimmerman,
Can I do a multiperiod OPF by this method, i.e. as the following code that
you have written?
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);
Regards
C. Gonzalez Almeida
