Feature

THE FUTURE OF RENEWABLE ENERGY TRANSMISSION: An Autonomous Energy Grid

steps of demonstrating these algorithms in real time for
real-world devices in the laboratory and now in smart
homes. Additional work will be needed in controls,
optimization, data analytics, complex systems, and
cybersecurity to implement the AEG across the entire
U.S. grid.

and operations of electrical power
systems. He has over 25 years of
experience in the design, testing,
and integration of renewable and
distributed power systems and has
more than 140 publications in these areas. Dr. Kroposki
received his BSEE and MSEE from Virginia Tech and Ph.D.
from the Colorado School of Mines. As an IEEE Fellow, Dr.
Kroposki was recognized for his leadership in renewable
and distributed energy systems integration. Dr. Kroposki
is the recipient of the IEEE Power & Energy Society (PES)
Ramakumar Family Renewable Energy Excellence Award.
Dr. Andrey Bernstein is the
manager of the Energy Systems
Optimization and Control Group
at the National Renewable Energy
Laboratory. He received the B.Sc. and
M.Sc. degrees (summa cum laude)
in electrical engineering and the
Ph.D. degree in electrical engineering
