The fuel-cost curves for a two generators power system are
Chapter , Problem 12.22(choose chapter or problem)
The fuel-cost curves for a two generators power system are given as follows: C1P1_ _ 600 _ 15 ? P1 _ 0:05 ? P1_ 2 C2P2_ _ 700 _ 20 ? P2 _ 0:04 ? P2_ 2 While the system losses can be approximated as PL _ 2 104 P1_ 2 _ 3 104 P2_ 2 4 104 P1P2 MW 686 C If the system is operating with a marginal cost (l) of $60/hr, determine the output of each unit, the total transmission losses, the total load demand, and the total operating cost.
