In a transmission scenario of 200 MW from Bus X to Bus Y with an 80% distribution factor, how much of the scheduled flow will go through transmission line X-Y?

To determine how much of the scheduled flow will go through transmission line X-Y, it's essential to understand the concept of a distribution factor. The distribution factor indicates the proportion of the total scheduled flow that will actually be transmitted through a specific line based on the system's configuration and impedance.

In this scenario, the scheduled flow from Bus X to Bus Y is 200 MW, and the distribution factor for transmission line X-Y is given as 80%. To find the amount of this scheduled flow that will go through the line, you would multiply the total scheduled flow by the distribution factor:

200 MW * 0.80 = 160 MW.

This calculation shows that 160 MW of the scheduled flow will indeed use transmission line X-Y, confirming that this is the correct answer. The significance of the distribution factor emphasizes that not all the scheduled flow may pass through a single line due to the physical and operational constraints of the system. Therefore, understanding these factors is crucial for effective power system operation and planning.
