The incremental cost characteristics of two generators delivering 200 MW are as follows:\(\frac{{d{F_1}}}{{d{P_1}}} = 2.0 + 0.01\;{P_1}\) and \(\frac{{d{F_2}}}{{d{P_2}}} = 1.6 + 0.02\;{P_2}\)For economic operation, the generation P1 and P2 should be

• A. 100 MW and 100 MW
• B. 80 MW and 120 MW
• C. 200 MW and 100 MW
• D. 120 MW and 80 MW
