Question

4.4 You are given three generating units and asked to find the optimal unit commit- ment schedule for the units to supply load over a 4-h time period. our MW Load 400 1000 1600 400 Gen 1: F(P) 2200+25P 0.025xP2 where 220s P, s600 MW Gen 2: F2(P)1500+P +0.02 x P2 where 350sP2s800MW Gen 3: F, B-l 000 + 20P, + 0.0 1 5 × P where 150 P, 600 Each generator has a start-up cost that must be factored in when the unit starts. You should assume that this start-up cost is incurred even if the unit was on then off for only one or two hours and then gets turned back on. Generating Unit Start-Up Cost 2400 3000 3400 Find the optimal unit commitment schedule.
