A power plant has two units with the following cost characteristics: Rs C = 0.7P? + 220P, + 2500 %3D Rs C = 1.3P + 160P, + 2700 where P, and Pa are the generating powers in MW. The daily load cycle is as follows: %3! 6:00 A.M. to 8:00 P.M. 150 MW 8:00 P.M. to 6:00 A.M. 60 MW The cost of taking either unit off the line and returning to service after 10 hours is Rs 5400. Maximum generation of each unit is 100 MW. Considering 24 hour period from 6:00 A.M. morning to 6:00 AM. the next day morning a. Would it be economical to keep both units in service for this 24 hour period or remove one unit from service for 10 hour period from 8:00 P.M. evening to 6:00 A.M. the next day morning ? b. Compute the economic schedule for the peak load and
