FOR NEARLY A CENTURY, GLOBAL POWER
systems have focused on three key functions: generating, transmitting, and distributing electricity as a
real-time commodity. Physics requires that electricity generation always be in real-time balance with
load-despite variability in load on time scales ranging from subsecond disturbances to multiyear trends.
With the increasing role of variable generation from
wind and solar, the retirement of fossil-fuel-based
