IEEE Power & Energy Magazine - May/June 2015 - 20

In the six
articles in
this issue,
the needs
for investing
in network
"smartness"
together with
reinforcing
the network
are debated.

funded by nedo and
several notable private
sector efforts. these
primarily demonstrated
high renewable penetration, islanding, reliability, and heterogeneous
power quality. Following the great east Japan
earthquake of 2011, the
major focus shifted from
microgrid to resiliency.
the objectives of those
projects did not include
resilience as a high priority; rather they were
intended to demonstrate
the high penetration of
local small-scale renewables, local control of
diverse resources, islanding, reliability, and heterogeneous power quality." they further emphasized that

"the exceptional performance of the Sendai
microgrid compared to
the legacy centralized
power grid during the
2011 earthquake and
tsunami changed perceptions and priorities
dramatically. Since that
time, microgrid development in Japan has been
resiliency focused, and
projects have expanded
beyond small sites, primarily commercial facilities, to more diverse
projects including larger
urban demonstrations, as
well as small community
systems." the article
talks about Japan's performance during
the 2011 event, the country's microgrid
research work, and concludes with the

role of resiliency in current research
and demonstrations including ongoing
projects. this is a fascinating article
filled with many details that should
capture the attention of all readers.
the fourth article, by Mathaios
Panteli and Pierluigi Mancarella,
focuses on the conceptualization of
the resilience of the future power
infrastructure via a conceptual curve
of the resilience level as a function of
time associated to a disturbance event.
in addition, it considers the long-term
adaptation as a key feature for achieving resilience. the aim to boost the
grid resilience to high-impact, lowprobability events "could be achieved
through resilience engineering for
enhancing the resilience of the network before and during the event
and disaster response and risk management for optimizing the response
following the event, which would

with CAPE 14 protection analysis software
Electrocon's CAPE (Computer-Aided Protection Engineering) software allows
utilities to determine if their networks are compliant with NERC PRC-019, PRC-023,
PRC-026 and other industry standards. The CAPE-TS Link™ option gives electric
power engineers a unique tool to evaluate the fast, wide-area control needed to
avoid cascading outages and blackouts. Realistic device models make CAPE the
most powerful protection simulation software available.
