I’m afraid I don’t have the time (or the information from you that I would
need) to look through the specifics of your case and interpret the results.
Presumably, there is some zero-cost generation (renewable?) that is marginal
during those hours. For example, if your wind has zero cost, and some of it is
being curtailed in those hours, that could set the nodal price to zero for
those hours. Answering the question of why it is optimal to curtain zero-cost
generation is question that would take more investigation on your part.
Regarding the total cost, you can get the value of the objective function from
mdo.results.f, but that includes other costs as well. To compute generation
costs, you would have to do it manually using the mpc for each period and, if
your problem is not deterministic, for each scenario/contingency (weighted by
the appropriate probabilities). That is, you can find the generator cost for
period t, scenario j, contingency k with the following …
mpc = mdo.flow(t,j,k).mpc;
total_cost = sum(totalcost(mpc.gencost, mpc.gen(:, PG)));
