a: All generators must generate equal power b: Total generation must equal total demand c: Incremental costs of all committed units must be equal d: Incremental costs of large generation unit must be larger

Incremental fuel cost is defined as:

a: Ratio of fuel input to generator output b: Derivative of generator's cost function with respect to its power output c: Difference between maximum and minimum cost d: Ratio of cost to load demand

Which of the following methods can be used for solving economic dispatch problems?

a: Newton-Raphson method b: Fast Decoupled method c: Gauss-Seidel method d: λ-Iteration method

5. If two generators have equal incremental costs but different fuel cost functions, then:

a: They share load according to their cost curves b: They must generate equal power c: The cheaper generator will supply full load d: The generator with lower penalty factor will supply more
