4.14 The incremental fuel costs for two generating units G, and G, are given by IC, = 25 + 0.2 PG, and IC, = 32 + 0.2 PG, where PG, and PG, are real powers generated by the %3D units. The economic allocation for a total load of 250 MW, neglecting transmission loss, is given by (a) PG, = 142.5 MW and PG, = 107.5 MW %3D %3D (b) PG, = 109.75 MW and %3D PG, = 1140.25 MW %3D (c) PG, = 125 MW and PG, = 125 MW %3D (d) PG, = 100 MW and PG, = 150 MW
