Dear Victor, If there is no congestion in the network, there is the same LMP at all the nodes. The LMP consists of loss, congestion, and energy costs. DCOPF has no losses, and if there is no congestion only the energy cost is accounted for. You can think of it as if since there is no congestion or loss cost the energy can be distributed to all nodes at the same price.
