A power system has two generators with the following total cost functions: Generator A: TCA = 5QA + QA2 Generator B: TCB = 30QB In the total cost functions, Q represents generator output. You may assume that the generators have no capacity constraints. Suppose that electricity demand during some hour was 10 MWh and that the utility running the power system uses economic dispatch to meet demand. Calculate the output for Generator B under economic dispatch.
