Q2. The three unit power plant has with the following cost functions:
fi = 0.52P,² + 220P, + 5100 $/h
%3D
f2 = 0.95P,2 + 275P2 + 5010 $/h
f3 = 0.72P3² + 164P3 + 9020 $/h
The maximum and minimum loads allowable on each unit are 150 and 39 MW. Find the economic
scheduling for a total load of a) 315 MW b) 205 MW (where P*; are the generating powers in MW).
