The aim of smart grids (SG) is quite broad and
we need to understand within the energy market, what are the demands and who
are interested. The name "Smart Grids" turned into a marketing and
its concept is very broad, so it is necessary to delimit the segments and we
will act when dealing with the matter. We can not say that our National
Interconnected System has no intelligence. However, we need to develop more?
What is really a SG?
Well, the aim of the smart grid is to provide
the network with a technological system that allows the consumer make the
choice about how and when to use energy more efficiently. Also, SG aims of
improving the operability of the electrical system, improve power quality,
reduce technical losses and commercial viable integration alternative sources
of energy distribution network, integrating storage systems intelligent power,
predicting failures the systems, using computer systems to provide demand
curves and thus assist in the commercialization of energy and facilitate the
growth of distributed generation and the free energy market. Finally, the SG comes
through automation, telecommunications and IT network, the total integration
between generation and end consumers. So we need to understand what the demands
of this vast market and which segments act.
So we can identify three macro markets, they
are: the Distribution of Energy, Distributed Generation and Energy Efficiency.
And what makes this complex market is the fact that the objectives of each of
these segments often have conflicting interests. It is therefore important, in
the large market of SG identify what matters to each segment.
Currently, in Brazil the infrastructure for
generation, transmission and distribution has been suffering with the
commercial and technical losses of energy due obsolescence of the network.
According to ANEEL (National Electric Energy Agency), the commercial losses
account for 8.7% of domestically produced energy, which equals all the energy
produced in the San Antonio plant. The expansion plan of Energy makes a
prediction of an increased demand by 54% between the years 2010 and 2019. With
an added benefit, the implementation of the Energy Efficiency Program and the
encouragement of distributed generation associated with smart grids can improve
capacity utilization and delay the need for investment in expanding the
Brazilian Electric System.
Furthermore, the development of smart grids in
Brazil can set a new benchmark for the electrical industry and can make the
market more dynamic power through new forms of actions of market players, which
includes the opportunity for users to operate both as producers and consumers
of energy.
From a business standpoint this fact
contributes to the expansion of the free market and emphasizes the adaptation
of market mechanisms of supply and demand by encouraging the effective
participation of small agents - consumers and producers.
Excellent explanation about SG....
