Question

For economic dispatch that neglects both line losses and generation limits _______.

• A. total generation is equal to the total demand.
• B. it is the most complicated economic dispatch problem.
• C. all the generators will share the load equally.
• D. all plants must operate at equal incremental fuel cost.

Hint:

In ideal dispatch (no losses or limits), generation equals demand. Losses are considered in real scenarios.

Answer 1

The Correct Option is A

Step 1: Simplified case
When line losses and generation constraints are ignored, the basic principle of power balance applies: \[ \sum P_G = \sum P_D \] Step 2: What is being ignored?
- Line losses: means the power sent = power received.
- Generation limits: all generators assumed to be capable of supplying any required amount.
Step 3: Interpretation
Under these assumptions, economic dispatch is solved such that generation equals demand directly.
