An area of an interconnected power system has three units operating on economic dispatch. The variable operating costs of these units (in $/MW hr) are given by : {200 Ci: 5P1 S200 + P1 + 0.02P? O = P1 < 100 100 = P1 < 300 Cz: 100 + 2P2 + 0.025P2 0 < P2 < 200 Cz: 100 + 1.5P3 + 0.04P3 0 = P3 < 250 where P1, P2, and P3 are in MW. ر What is the optimal scheduling for a load of 300 MW, and what is the total operating costs (in $/MW hr)? (Hint: this problem considers the generation limits. It will be helpful to figure out which lambda region will cover the given level of load.)
