IEEE Power & Energy Magazine - March/April 2018 - 22

in the following article, a group of
authors from RTe france presents a
number of crucial developments in the
eMs area: 1) the use of the large-scale
grid as a smoothing mechanism (expansion in large systems), 2) dynamic load
management, 3) the optimal use of the
system by operating the grid closer to
its limits and taking minimal preventive
margins through the full use of all grid
control variables (topology and management of transmission flows and voltage),
4) the implementation of power storage
strategies, and 5) pooling different energy systems into one delivery ecosystem.
in response to such challenges, the authors describe eMs functionalities that
will be implemented in the RTe control center in 2018 as well as the smart
substation design, which is already operational in one substation and will be
rolled out in subsequent years to others.

in the eMs realm, emphasis is on
the proactive and action-oriented tools
to improve short-term planning (Day
+ 2) ahead. They are also focused on
tools to address uncertainties. The smart
substation design has some unique fast
communication features with redundant
communication protocols and low-power
instrument transformers that facilitate
digitalization in the substation switchyard for more reliable measurements
during dynamic transient conditions.
The authors' goal is to achieve a selfhealing design that will also offer
much higher sampling rates and entail
an open platform design. Their focus
is on improved monitoring techniques
for asset assessment. They also consider acquiring more weather-related
data from specialized sources. Consequently, they see computational resources as necessary enhancements

to deploy new data analytics intensive functionalities.
The final article is from an advanced
DMs (aDMs) vendor and coauthored
by one of its customers, Duke Power
Company. This article articulates some
of the leading features used in DMss
today: monitoring and control, loss
optimization, distribution system demand response, emergency control, and
storm tracking. The authors focus on an
elaborate solution for volt/var optimization integrated with the near-term load
forecasting, load flow, and state estimation. They propose a very rich design of
aDMs functionalities to meet custom
demands in different DMs environments. The design framework integrates
traditional grid monitoring, analysis,
operation, and management with fault
location, isolation and supply restoration, as well as the outage management
