The incremental fuel costs for two generating units G1 and G2 are given by Ic1 = 25 + 0.2 PG1 and Ic2 = 32 + 0.2 PG2, where PG1 and PG2 are real powers generated by the units. The economic allocation for a total load of 250 MW, neglecting transmission loss, is given by

PG1 = 109.75 MW and PG2 = 140.25 MW

PG1 = 142.5 MW and PG2 = 107.5 MW

PG1 = 125 MW and PG2 = 125 MW

PG1 = 100 MW and PG2 = 150 MW

PG1 = 109.75 MW and PG2 = 140.25 MW

PG1 = 142.5 MW and PG2 = 107.5 MW

PG1 = 125 MW and PG2 = 125 MW

PG1 = 100 MW and PG2 = 150 MW
