Solved Example Problem 29 - Economic Load Dispatch with Daily Load Cycle #psoc

A power plant has two units with the following cost characteristics: C1 = 0.6 P1^2 + 200 P1 + 2000 Rs / hour C2 = 1.2 P2^2 + 150 P2 + 2500 Rs / hour Where P1 and P2 are the generating powers in MW. The daily load cycle is as follows 6:00 A.M. to 6:00 P.M. 150 MW 6:00 P.M. to 6:00 A.M. 50 MW The cost of taking either unit off the line and returning to service after 12 hours is Rs 5000. Considering 24-hour period from 6:00 A.M. one morning to 6:00 A.M. the next morning. (i) Would it be economical to keep both units in service for this 24-hour period or remove one unit from service for 12-hour period from 6:00 P.M. one evening to 6:00 A.M. the next morning? (ii) Compute the economic schedule for the peak load and off-peak load conditions. (iii) Calculate the optimum operating cost per day. #powersystemoperation #psoc #problemsolving #eee #annauniversity #jntu #osmaniauniversity #iit #nit #cbit #problemsolved #powersystemanalysis #powersystem #powersystemoperationcontrol #semester #finalyear #importantquestions #electricalandelectronicsengineering #economicloaddispatch #eldproblem #VIT #SRM #KLuniv #university #economicloaddispatch #EE #computerelectricalengg #eldloss #viral #economicloaddispatch #powersystemeconomics #powersystemoperation #semesterexam #endsemesterexam #electricalandcomputerengineering
