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
Correct answer
(A) solution of economic load dispatch
Solution
In load flow analysis, a PV bus (also known as a generator bus) is one where the real power and the voltage magnitude are specified. The value of the real power to be generated at these buses is typically determined by the Economic Load Dispatch (ELD), which calculates the optimal power output of each generator to meet the total system load at minimum cost while satisfying system constraints.
