Consider a three-units system presented bythe cost function as:C1 = 0.03 P12 + 8.2P1 + 452C2 = 0.025 P22 + 8.3P2+ 500C3 = 0.0035 P32 + 7.44P3 + 612Where P1, P2 and P3 are in MW and thetotal load demand, PD is 952 (in MW).(a) Compare these three-units system withand without the economic dispatch bydrawing the bar graphs for the power ofeach plants and the total cost in RM/h.(b) Determine the percentage of saving,with and without the optimal economicdispatch. Discuss the answer.(c) Now, P1, P2 and P3 are subjected to thefollowing limits:50 MW < P1 < 300 MW100 MW < P2 < 400 MW100 MW < P3 < 350 MWCompare with the costs in (a). Justify theanswer.

Given cost function, C1 = 0.03 P12 + 8.2P1 + 452C2 = 0.025 P22 + 8.3P2+ 500C3 = 0.0035 P32 + 7.44P3…

Old Pueblo Engineering Contractors creates six-month “rolling” schedules, which are recomputed monthly. For competitive reasons (it would need to divulge proprietary design criteria, methods, and so on), Old Pueblo does not subcontract. Therefore, its only options to meet customer requirements are (1) work on regular time; (2) work on overtime, which is limited to 30 percent of regular time; (3) do customers’ work early, which would costan additional $5 per hour per month; and (4) perform customers’ work late, which would cost an additional $10 per hour per month penalty, as provided by their contract. Old Pueblo has 25 engineers on its staff at an hourly rate of $30. The overtime rate is $45.
