Since MATPOWER represents dispatchable demand as negative generation with
negative cost, the objective function ends up being the negative of net
benefits. Normally you want to maximize net benefits (total benefit to demand
minus total cost of supply). MATPOWER does this by minimizing the negative of
net benefits. So a negative objective function silly means that the benefits to
the loads is greater than the cost to generators … which is what you normally
expect.
