12.3 What is the merit order used for when applied to generator scheduling? A power system is supplied by three generators. The functions relating the cost (in £/h) to active power output (in MW) when operating each of these units are: C₁ (P₁) = 0.04P+2P₁ +250 C₂ (P2) = 0.02P2+3P₂ + 450 C3(P3) = 0.01P3 +5P3 +250 The system load is 525 MW. Assuming that all generators operate at the same marginal cost, calculate: a. the marginal cost; b. optimum output of each generator; c. the total hourly cost of this despatch. (Answer: (a) £10/MWh; (b) P₁= 100 MW, P₂=175 MW, P3=250 MW; (c) £4562.5/h)
