I had a little discussion with a friend about how reactive current influate voltage drop in a distribusion line.

The case:

If I have a generator on one side of a line and a load on the other side. The load needs a specific voltage. Now, I'd need a bit higher voltage on the side with the generator because of the loss in the line. But let's say there was something close to the generator which couldn't handle the extra voltage (another load. f.ex). That means I can't have (much) higher voltage on this side. Then my friend claims that we could minimize the difference in voltage by making a reactive current flow through the line.

I've had some about impedance, reactive current, i etc.. But I don't have a clue about this one. Anyone can tell me about this?

If something is wrong or unclear, please excuse me, I'll trye to explain as good as possible! :)
