The fuel-cost curves for a two generator system are given as follows:
C1(PG1) = 2000 + 45 * PG1 + 0.05 * (PG1)2 C2(PG2) = 500 + 50 * PG2 + 0.03 * (PG2)2 Generator limits are: 0 ?PG1 ?200 200 ?PG2 ? 800 For a load of 600 MW, use the lambda iteration method to determine the values of ?M, PG1(?M) and P G2(?M) after two iterations. Show the values of all variables at each iteration. Use starting values of ?L = 60 and ?H = 80. Be sure to consider the generator limits; you may ignore any penalty factors.
