Over time, a larger proportion of electronics are constant-power loads, while they used to be constant-resistance. Will this lead to an unstable grid? If not, why not?
Constant power loads at home are battery chargers, TVs, many appliances.
In a constant-resistance environment, the grid is self-regulating to a certain extent, as if power generation cannot match power consumption, then a slight drop in voltage would reduce the consumption.
In a constant power environment, this self-regulation would not exist, as a slight drop in generator voltage would just lead to an increased current draw and a constant power consumption. This sounds like it would lead to a run-away process if left unchecked.
