The nation’s electric power system is undergoing a major transformation in many ways, including:
- the increase and integration of new devices, including distributed energy resources (distributed generation, electric vehicles, energy storage),
- a major shift in generation mix (more renewable resources with non-firm power),
- aging infrastructure, and
- greater customer involvement, (demand responsive systems and programs).
To manage the capabilities of the grid’s increasing number of assets, this transformation requires greater “visibility” throughout the electric power system. Meeting this goal will require the capability to accurately measure and characterize the state of the power system at much higher fidelity and resolution than ever before—from generation, to transmission and distribution, and finally to end-load use. A cohesive strategy is needed to prioritize DOE’s research, development, and deployment activities in this important area.
