Electrical Engineering XYZ MCQs
If the penalty factor of a plant is unity, its incremental transmission loss is:
- 0
- -1
- 1
- None of the above
Correct answer: 1. 0
Explanation:
- The penalty factor of a plant in the context of power systems refers to a parameter used in economic dispatch, which is the process of allocating generation among various generators to meet the load demand at minimum cost while satisfying operational constraints.
- When the penalty factor of a plant is unity, it means that there is no additional cost associated with increasing or decreasing the generation from that particular plant. In other words, the cost remains constant regardless of the amount of power generated.
- In this case, since there is no cost associated with changing the generation level, there is no incremental transmission loss incurred. Incremental transmission loss refers to the additional loss in power transmission that occurs when there are changes in generation levels.
- Therefore, the correct answer is 0.
