Two generating units have the following characteristics: Unit 1 (Gas): H,(P1) = 100 + 4*P, + 0.002*P,2 50 MW < P, < 500 MW Unit 2 (Coal): H2(P2) = 300 + 6*P2 + 0.0025*P22 50 MW < P2 < 400 MW The fuel costs for the units are as follows: Gas: 0.6 $/MBtu The coal costs 14 $/ton and has an average heat content 12500 Btu/lb (1 ton = 2000 lb) Unit 2 is on a take-or-pay supply contract and must burn 500 tons of coal during the 8-h time period. Assume both units are on-line and they should meet the following load: Period Duration Load (MW) 1 4 hours 400 4 hours 650 For a starting value of y = 12 $/ton, In iteration 1, the coal consumption of unit 2 during time period 2 is equal to: Select one: O a. 368.48 tons O b. 352 tons O c. 284.25 tons O d. None of these
