A conference on HTS SMES was held in Japan in December 1998. The proceedings are in
Japanese. Summaries of some of the papers are given here.
I Masahiro Yamamoto provided an overview of the ISTEC/SMES Project,
The SMES system can store energy as electricity and has a highly efficient energy storage
capability. Moreover, it allows high-speed input and output of energy, which means both real
and reactive power can be controlled independently. Other features determine that it has high
capabilities, not only in energy storage capacity aspects (kWh), but also in aspects of
instantaneous output of electric power. It is anticipated that the SMES system will fulfill a
significant role in future electric power systems in terms of load-leveling of power, load change
compensation, improving system stabilization, etc.
Due to these factors, the Japanese government, electric power companies, manufacturers, and
research groups concerned with superconducting energy storage are engaged in investigation,
research, and conceptual design work on its utility.
The Agency of Natural Resources and Energy, Ministry of International Trade and Industry, has
taken the first step toward full-scale development of SMES in Japan. It is conducting a project
'Study of Factors and Technology Development for Superconducting Electric Power Storage
System' during fiscal years 1991-1998 to establish the necessary technological basis for building
a small-scale SMES pilot plant. As shown in Table IX, ISTEC is consigned to implement this
with the participation of electric power companies and manufacturers. In addition, in order to
promote effective research, an advisory committee of experts in the field has been set up to
examine and review the content of the studies.
