‘Living lab’ provides blueprint for sustainable
residential electrical systems that could reduce emissions by 55%
and save homeowners up to 44% of annual energy costs
Purdue University is using global software and engineering
leader Emerson’s (NYSE: EMR) advanced digital technologies to
automate its Nanogrid House, a living lab for energy-efficient home
research. Compared to today’s homes and businesses that are powered
predominantly by alternating current (AC) power, the Nanogrid House
can shift between AC and direct current (DC) power, which increases
the ability to use renewable energy and lowers homeowners’ energy
costs.
High-voltage AC power from the grid must be converted to DC
power to run household devices, wasting time and money. And while
new renewable energy sources such as solar and wind deliver DC
power directly, this power is not compatible with existing home
electrical infrastructure. The Nanogrid House enables researchers
to develop technologies to address these challenges in anticipation
of a future nationwide shift to DC power.
"As we continue to face extreme weather, a DC-powered home is
uniquely suited to the future of energy generation, empowering
homeowners to turn their houses into nanogrids of efficient,
self-sufficient production and consumption,” said Bob Yeager,
president of Emerson’s power and water business.
Using Emerson’s renewable power expertise and Ovation™ software
and technologies, Purdue University researchers have retrofitted an
entire house to run on its own DC-powered nanogrid. The nanogrid
integrates both AC power from local electric utilities and DC power
from solar panels, wind turbines or battery storage.
These sustainable energy sources help reduce the house’s carbon
footprint by an estimated 55% and lower annual energy costs by up
to 44%. The Nanogrid House can also sustain itself for short
periods of time by generating its own renewable energy and
detaching from the grid through the help of on-site stored
energy.
“As consumers add sustainable, DC-based electrical solutions to
their homes, the need for a low-voltage, more energy efficient
infrastructure will continue to increase,” said Eckhard A. Groll,
William E. and Florence E. Perry head of mechanical engineering and
Reilly professor of mechanical engineering, Purdue University.
“Emerson’s expertise in automation software for power generation
and sustainability helped us design a DC nanogrid solution that may
someday become the national standard.”
Emerson’s Ovation™ software and technologies provide the project
with a digital automation foundation integrating data provided by
the home’s energy generation, heat and cooling production and
battery storage assets. Ovation software operates as the “brain” of
the home by managing voltage control, power distribution and load
and intelligently optimizing operation of the nanogrid
equipment.
