Electric power grids around the world are becoming increasingly stressed by factors including inadequate transmission growth, system operators and power engineers retiring in large numbers, and integration of renewable sources of energy whose physics is different from well-known sources such as hydro and coal. All these factors, and more, can be mitigated by greatly increased sharing of sensor data between utilities (and independent system operators [ISOs]/regional transmission organizations [RTOs]) in a grid, something that is extremely limited in power grids today. This is an important step in helping make grids more resilient, because inadequate situational awareness resulting from little interutility data sharing has been a major contributing factor in virtually all recent major blackouts. In such blackouts, there are always a few physical or operational root causes that are blamed. However, due to the poor situational awareness, the grids’ operators are unaware of emerging problems until it is too late to prevent a blackout.
