“How can we prevent a grid overload using a simple technique?”
We have a problem. We would like the demand usage for the electric grid to be as equalized as possible, such that the electricity drawn in at one time would look the same as the electricity drawn in at another. But this is almost never the case. Instead, the demand for the grid varies greatly throughout the day. And sometimes these demand peaks are so high that they destabilize the grid! So how can we use our engineering mindset to solve this problem? Well, what if we were to just shift electricity usage from times of peak load to times of less intensive load? This is the fundamental idea behind demand response and can be accomplished with economic incentives and through smart electricity control.
