Out of the following options, the most relevant information needed to specify the real power (P) at the PV buses in a load flow analysis is

  1. solution of economic load dispatch
  2. rated power output of the generator
  3. rated voltage of the generator
  4. base power of the generator

Show answer and explanation

Correct answer: (A) solution of economic load dispatch

Explanation

At a PV bus the real power is scheduled, and the schedule comes from the economic load dispatch solution, which decides how much each generator should produce.
