IEEE Power & Energy Magazine - January/February 2016 - 31
E
energy policies, both present and
future, are creating a substantial transformation
of the electrical power grid and pose significant
challenges to the transmission and distribution
it systems needed to control and manage this
grid. as more critical business processes are
automated and new devices and systems added
to achieve the smart grid vision of the future,
the challenge rapidly becomes one of having too
much data from a variety of new and incompatible sources but too little information.
the solution to this dilemma is the development of an overarching framework with the goal
of facilitating interoperability between the many
disparate systems comprising the smart grid. in
this issue of IEEE Power & Energy Magazine, we
highlight one of the most promising solutions to
achieving this framework, which is based on the
widely deployed international electrotechnical
commission (iec) common information Model
(ciM) standards. the articles in this issue provide
background information and explain the need for
having interoperable solutions across the entire
electrical energy landscape and the efforts already
underway in this area.
Moving Environment
today's electricity landscape is changing faster
than ever before. generation patterns are shifting
due to the replacement of old fossil-fueled plants
with natural gas and renewable energy sources
(ress), resulting in more variability over time,
more dependence on weather conditions, and
widely dispersed energy sources throughout the
power network. this scenario has resulted in the
need for better prediction and control to maintain
the security of supply. increased cross-border
flows as the result of merging energy markets
are increasing system complexity. consequently,
demand needs to become more flexible, and the
call for competitive electricity prices and a reliable system becomes even more essential. this,
in turn, impacts all areas of system planning and
operation and will require major changes in the
market's organization and products.

this changing environment requires us to
challenge current assumptions about the needs of
power system users, and a new road map will be
required for the development and operation of the
power system over three time horizons: short term
(one to five years), medium term (six to 15 years)
and long term (over 15 years).
the long-term european energy vision supported by the recent european commission (ec)
communication on the energy Union requires a
paradigm shift that must be addressed at the paneuropean level. Uncertainties derived from the
large amount of variable ress to be integrated,
including offshore generation, new consumption
demands, the inclusion of demand-side response,
and energy storage, create a set of possible scenarios that, in turn, lay the foundations for increasingly
more novel infrastructure planning approaches and
coordinated system operation at the pan-european
level, all supported by a well-adapted market design.
similarly, the smart grid vision as articulated
by national institute for standards and technology
(nist) foresees a major transformation of "... the
Usa's aging electric power system into an interoperable smart grid-a network that will integrate
information and communication technologies with
the power-delivery infrastructure, enabling twoway flows of energy and communications." Figure 1,
which is a conceptual model of the smart grid, consists of seven domains, and each contains multiple
applications, roles, and associations realized via
secure information exchanges (or communication
flows). in some countries, there is also an electrical
flow from customer direct to transmission.
Figure 2 illustrates the complexity of the underlying communication paths both within and between
domains (of course, this is just a small sample of the
many systems actually exchanging information in
the real world). the goal is interoperability between
all the systems/devices across all domains.
Need to Adapt to the New Rules
the fight against climate change together with
the achievement of the internal electricity market
(ieM) in europe requires new rules, new technologies, and new ways of operating the power system. integration among all players, be it generators, consumers, distribution system operators
