Question
Two generating units have the following characteristics:
Unit 1 (Gas):
H,(P,) = 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
