asserts that community microgrids,
with the aim of supplying electricity
for a group of consumers in a neighborhood or several connected neighborhoods with close proximity, have
emerged as an alternative to address
the rising societal demands for electric infrastructures that are able to
provide premium reliability and
power quality levels while being economic and environmentally friendly.
The authors discuss the components
of community microgrids and elaborate on the benefits and issues with
the development of community
microgrids. The authors advocate that
community microgrids could be
deliberated as viable solutions to
pressing challenges of economy, reliability, and environment while providing unprecedented benefits for
local consumers as well as the power
system as a whole. Community
microgrids would be built upon the
existing utility distribution network;
hence, these deployments would not
be successful unless fully supported
by utility companies. As microgrid
technology becomes more viable and
advantageous, utility companies will
need to be more involved to ensure
sustainable deployment, to the point
that utilities could ensure benefits
and become promoters of community microgrids.
Commonwealth Edison (ComEd),
the electric utility company in the
greater Chicago area, has been recently
awarded a grant from the U.S. Department of Energy to develop a microgrid
master controller with applications to
community microgrids. A selected
group of leading authorities from manufacturers, consulting firms, software
developers, universities, and national
labs active in the power and energy
industry will be led by ComEd in this
effort. This work not only provides
