Consider the following information for two generators: Table 1: Generation Characteristics Generator Cost Pmin - pu Pmax-pu f1(P) = 4P1 0.2 f2(P)=7P2 0.1 Assume that these generators are providing a load of P 1 pu and that the losses in the (a) (2 points) Setup (no need to solve) the economic dispatch problem to find the opti- network can be modeled by Ploss -0.02 P1 +0.01 P2. mal powers Pt and P that minimize the cost to supply the loads while meeting all the constraints 02/28/13 2.
