geomagnetic interferences. The authors
point out that resiliency considerations
have to be incorporated into eMs design
and also reflected in the market management system (MMs), and the two
solutions need to be well coordinated to
account for the resiliency arrangement

between the physical electricity grid and
its market conditions. The authors propose that risk-based metrics and predictive features should become part of eMs
and DMs design in the future to allow
utility staff to make informed decisions
under unfolding threats in the planning

Don't just pass Enter the
on paper real standard
There is a big difference between
a test and the best. Without real
laboratory testing, you can only
show performance on paper -
it can't test whether your new
breakthrough product will function
reliably in the real world. To meet
the real standards of today's highpowered world and get full access
to the global energy market, you
need an independent laboratory
test that proves your product's
true performance.

At our KEMA Laboratories, 25%
of the products do not initially
pass the test. For more than 90
years, our experts have guided
precise and secure testing and
adjustments to get your product
ready for the global market.
Visit us at Booth 3647 at the
IEEE PES T&D Conference to
learn how our laboratory testing
ensures your product meets the
highest international standards
and is tested for the highest
performance.

and operations stages as well as outage and asset management realms.
They also suggest that future eMs/DMs
designs should allow a systemwide view
over the entire interconnection, with
closely coordinated actions among operations, protection, and asset management,
which is not traditionally done today.
The second article is prepared by a
group of authors from Tsinghua university and a former chief engineer
at the state grid in China, who were
intimately involved in the development
of Chinese eMs systems for over a decade. They point out that the new requirements to serve large-scale centralized
systems consisting of many regional
grids imposes critical considerations
of built-in cybersecurity measures and
standardization such as service-oriented
architecture and the Common information Model. They also suggest that
modern eMs design should benefit from
synchophasor technology for certain applications, and they are exploring how integration among supervisory control and
data acquisition remote terminal units
and phasor measurement units may complement each other. They have focused
on the smart grid operation system recently pursued by both the state grid and The
southern grid, the two major state power
companies in China.
The new architecture focuses on horizontal integration and vertical penetration meeting the need to integrate
relevant functionalities across multiple
departments (horizontal integration)
and coordinate operation among hierarchically positioned control centers in the
various provinces (vertical penetration).
Their use of the virtual private network
assures the required separation between
various security zones and yet allows for
fast communication across different control system layers. The goal is to use an
open platform for future developments
and expansion of the system design and
allow for the integration of products
from different vendors. The final message the authors convey is that further
developments are needed: "Much more
R&D work has to be done in the future,
especially in dedicated control cloud,
