How to ramp up a factory consuming a lot of energy?
One question about the grid I've never wrapped my head around:<p>So the entire grid is in phase, by which I mean every generator, load, &c is operating on the same AC pulse (<i>handwave-handwave</i> ignoring smaller loads, transformations, etc.). But that phase isn't instantaneous; it's near-light, and the grid is long enough for that to matter in places.<p>So every point in the grid can't be perfectly in phase with every other point, right? Because we have both lightspeed delays and loops, so even if point A is receiving power from two substations in-phase, point B (with different lengths of wire to those two substations) should be receiving it out-of-phase, right? How do we balance that in the grid?
