distributed real-time big data, global
grid operation, etc."
The next article is from Japan, authored by staff members from Chubu
electric and a professor from Toyo university with extensive experience in
the vendor environment. it addresses
the important issues that came out of recent electricity sector reform in Japan:
establishing the cross-regional coordination of transmission operators to enhance
nationwide system operations in 2015,
a full retail choice and full liberalization of wholesale power generation in
2016, and further securing the neutrality of the transmission and distribution sector through legal unbundling
in 2020. such reforms were also driven
by the fukushima Daiichi Nuclear
Power station disaster as well as the
rapid deployment of photovoltaic (PV)

distributed generation. in meeting such
requirements, eMs and DMs designs
were integrated, and further assimilation with a future independent market
operator is envisioned.
it is well known that the Japanese
industry is always looking at new technologies to solve complex problems, so iT
solutions are the main focus of the article.
The Chubu electric special design in the
planning area interfaces transmission system operators, organization of CrossRegional Coordination of Transmission
operators, and Japan electric Power
exchange to optimize the nationwide
network operation. Chubu electric eMs
and DMs designs are merged since the
utilities still own both transmission and
distribution segments of the grid.
Due to the penetration of renewables,
particularly solar PV generation, their

central dispatch center has an extensive
PV output forecast system connected
to the Japan Meteorological agency
for continuous monitoring of solar radiation and other weather conditions. a
new control and protection system prevents cascading events as a part of the
eMs/DMs design. They are also using
internet Protocol networks and anticipate integrating data across substations
and feeders, including smart meters and
specialized sensors. The authors discuss
the importance of integrating dispersed
databases for asset management, diverse
iT systems, and geographic information systems, resulting in an iT system
for transmission planning, operation and
maintenance. The final goal is the integration of eMss and DMss with enterprise resource planning and enterprise
asset management systems.
