IEEE Power & Energy Magazine - May/June 2015 - 18

This issue
includes six
excellent
articles about
the on-going
efforts around
the world
to accord
resilience to
electric power
grid.

developed to exploit the
grid's renewable energy
resources to face climate change challenges
and enhance its security
of energy supply. As
shown in studies, a shift
from a member-statecentric to an eU-wide
approach to decarbonizing the electricity system enabled by an eU
megagrid would bring
very significant benefits in integrating solar
generation in the south
and wind generation
in the north of europe.
Moreover, this vision
should be supported by the application
of smart grid concepts and technologies
in distribution networks to enhance the
cost effectiveness and resilience of the
future eU system. "in this context," the
authors state, "microgrids, with appropriat enabling technologies, will facilitate

national r&d effort on
grid resilience, doe adopts
a public/private partnership
approach to join with key
stakeholders in developing
and implementing a resilient grid r&d plan. this
article presents the plan
development process and
key elements of the developed plan, including r&d
focus areas and associated
priority activities identified
as necessary for pursuit of
the defined resilience goals.
examples of ongoing projects supported by the doe
in developing resilience
metrics and assessment and
modeling tools for resilience are provided. Further, the planned activities for
out years are outlined."  
the second article, by Strbac et al.,
focuses on the role of microgrids in
enhancing the resilience of the european megagrid. resiliency needs to be

the paradigm shift in delivering resilience
and security of supply from redundancy
in assets and preventive control to more
intelligent operation through corrective
control actions supported by a range of
enabling technologies and ict." the
article describes the control challenges for
the effective operation of microgrids both
in interconnected and islanded operations,
including the effects of communication
malfunctions, and focuses on their role in
power system restoration. the shift from a
centralized to a fully decentralized operation paradigm for enhancing real-time
control of microgrids to improve supply
resilience and quality of service delivered
to end consumers is discussed.
the third article deals with the
efforts to improve the resiliency of the
power grid in Japan. chris Marnay and
his associates in Japan have been focusing their work in this area for almost a
decade. in 2006, Japan took the early
lead in focusing work on microgrid
research. in the authors' words, "this
was driven by four demonstrations
