Indeed, the US grid has set the absolute standard for scale and performance of engineered systems for more than a century, but new technologies, economics, social attitudes, and environmental sensibilities are calling this model into question. Rapidly falling costs of distributed electricity generation methods such as solar photovoltaics and storage technologies coupled with the growing emphasis on improving electric power system resiliency have motivated the investigation of alternative architectures for planning and operating electric power systems.

A building energy management system may control rooftop photovoltaic or gas-powered combined heat and power technologies, loads, energy storage, and purchases from or sales to the grid. It is an electrical grid in every sense except scale and presents many of the same problems in optimal control.

As new technologies enable a more efficient grid, the fiction of a static grid -- designed to a fixed point and then simply operated as designed -- will be further undermined. A campus or individual building in an office park may sometimes operate autonomously, sometimes focus on local coordination, sometimes operate as part of a much larger whole.

TECHNICAL CHALLENGES Rearchitecting the control of electric power systems will not be achieved quickly or simply. Indeed, the study of grid architecture is emerging as an important new research domain (e.g., Taft and Becker-Dippmann 2015)

The power lectronics–based e inverters that interface with distributed energy resources such as photo oltaics or v storage devices will play an increasingly important role in enabling more precise control of the system. ADVANCED ANALYTICS A new generation of electricity system data analytics is needed (National Academies 2016)

But significant research and development are still needed to determine how to optimally integrate all the required component technologies. A particular challenge will be harmonization of this vision for future grid operation with the reality of continuous incremental change, which is necessary to the engineering of all critical infrastructure technologies.
