Questiоn 6. (30 pоints): There аre three generаtоrs in this system аnd the load is 1000MW. Variables: G1: Real power generated by generator 1 G2: Real power generated by generator 2 G3: Real power generated by generator 3 U1: Unit commitment (binary) variable representing generator 1 (U = 1: On, U = 0: off) U2: Unit commitment (binary) variable representing generator 2 (U = 1: On, U = 0: off) U3: Unit commitment (binary) variable representing generator 3 (U = 1: On, U = 0: off) Costs: The total cost function of Generator 1 is: 20G1 + 6000U1 The total cost function of Generator 2 is: 45G2 + 5000U2 The total cost function of Generator 3 is: 50G3 + 4000U3 Solve the following problem to determine the values of G1, G2, G3, U1, U2, and U3. Determine the total operating cost. Minimize: 20G1 + 45G2 + 50G3 + 6000U1 + 5000U2 + 4000U3 Subject to: 300*U1 ≤ G1 ≤ 400*U1 350*U2 ≤ G2 ≤ 500*U2 400*U3 ≤ G3 ≤ 1200*U3 G1 + G2 + G3 = 1000 U1
