Unit 1: Coal-fired steam unit: Max output = 600 MW Min output = 150 MW Input-output curve: Input-output curve: H₁ Unit 2: Oil-fired steam unit: Max output=400 H₂ Input-output curve: MBtu = 510.0+7.2P, +0.00142P² MBtu h MW Min output - 100 MW =310.0+7.85P +0.00194P² Unit 3: Oil-fired steam unit: Max output = 200 MW Min output = 50 MW H₁ (MBtu)- = 78.0+7.97P, +0.00482 P² h Example 3A: Suppose that we wish to determine the economic operating point for these three units when delivering a total of 850 MW. Before this problem can be solved, the fuel cost of each unit must be specified. Let the following fuel costs be in effect. Unitl: fuel cost = 1.1 $/MBtu Unit 2: fuel cost=1.0 $/MBtu Unit 3: fuel cost=1.0 $/MBtu

Before this problem can be solved, the fuel cost of each unit must be specified. Let the following fuel costs be in effect. Unit1: fuel cost-1.1 $/MBtu Unit 2: fuel cost=1.0 $/MBtu Unit 3: fuel cost=1.0 $/MBtu
