were introduced.

asia 3 Session
The Asia 3 session included four presentations, from Taiwan, Japan, and China. The first speaker was Raymond
Yung-Ruei Chang from the Nuclear Instrumentation
Division of the Institute of Nuclear
Energy Research, Taiwan, who introduced the institute's recent research,
especially its microgrid demonstration. Its goal is to develop power control and management technology for
the low-voltage side of smart
microgrids, in which 20% of total
energy comes from renewable energy.
The latest demonstration results
were introduced from power system
technology, power electronics, and
energy management system aspects.
The second presenter, Hirohisa Aki
from the National Institute of
Advanced Industrial Science and Technology, Japan, gave an overview of a
recent white paper, "Microgrids for Disaster Preparedness
and Recovery with Electricity Continuity Plans and Systems,"
which was published by the International Electrotechnical
Commission (IEC) in March 2014. The importance of
microgrid technologies for power supply resiliency has come
to be recognized after several recent large disasters, for
example, the Sendai Microgrid in Japan demonstrated excellent resiliency following the 2011 East Japan earthquake.
The third presenter, Yuko Hirase from Kawasaki Technology Co., Ltd., Japan, introduced the company's recent
research on the Virtual Synchronous Generator, technology that is used to implement the virtual inertia and droop
characteristics on an inverter-interfaced distributed gener-

ator. The presentation was well organized and covered the
development process from the theoretical explanation of
the developed control strategy to actual field test results.
The last presenter, the Chinese Academy of Sciences'
Lei Huang from Guangzhou Institute of Energy Conversion, introduced the Dong'Ao island demonstration, which
consists of 50 kW of wind power generators, 1 MW PV, a
1-MW diesel generator, 1.5 MWh of lead-acid batteries,
and a 100-kW ice machine employed as responsive load.
The development results of a wind-
PV-diesel hybrid optimized planning,
energy management scheme, remote
real-time monitor and control, and
development of a high power bidirectional converter were given.
The symposium organization by
Chairs Meiqin Mao and Chengshan
Wang together with Tao Xu and other
members of the Local Organizing
Committee was flawless. At the end of
the first day, a delicious Chinese banquet was served, and attendees were
treated to a tremendous traditional
Chinese music concert by a Tianjin
University student group (Figure 3).

The point was made
that standards
should be flexible
to enhance design
during development
by saying that we
are all learning
together.

americas Session
The Americas Session included two parts. The first included
three presentations that provided a comprehensive overview of microgrid RD&D in the Americas. Ross Guttromson
from U.S. Sandia National Laboratories delivered a presentation on behalf of the U.S. DOE-OE that highlighted its
microgrid-related activities and programs. The focus of the
presentation was on three items, i.e., the development of
commercial-scale microgrid systems, microgrid design tool
sets for designers and planners, and microgrids as a resiliency resource. Hassan Farhangi from the British Columbia
Institute of Technology, Canada, delivered a presentation
that described microgrid-related RD&D and demonstration
