Smart Cities
The implementation of micro grids
is, basically, a step towards the
creation of ‘smart cities’. A city in
which all the infrastructure, road and
municipal services, surveillance and
warning systems are transformed
into a single system, needs micro
grids. All parts of the urban system
interact with each other and make
the most efficient use of resources
to fulfill their tasks. All this
became possible by virtue of the
development of digital technologies.
‘Smart City’ uses several micro
grids connected to the distribution
system. This fully integrated system
includes alternative energy sources
and stores a surplus of electricity
generated.
At the international exhibition
‘EXPO-2017’ Siemens introduced the
micro grid technology. Through the
example of the city of the future,
visitors themselves could build an
energy grid system, that would allow
the city to function successfully.
Anyone who feels like he or she
wants to get acquainted with these
technologies has the best opinion of
our specialists.
Smart grids
At the current date, there is an
active implementation of the ‘smart
grids’, which is an important step
in the way of decentralization
of energy. ‘Smart grids’ combine
modern energy capabilities with
digital innovations to successfully
manage the entire power grid.
Careful calculations reduce power
losses and ensure the continuity of
power supply. A distinctive feature
of 'smart grids', is self-diagnostics
and self-recovery, which enables
the system to detect emergency
areas of the grid and automatically
reorganize.
Consumers benefit greatly from
the implementation of ‘smart grid’
technologies. Emergency situations
occur less frequently, and the
work of the damaged area can be
restored more quickly. For example,
earlier, in the case of a short circuit,
the dispatcher had to wait for a
call from the consumers, search for
the necessary problem and analyze
the information by himself. Today
things are going much more quickly:
there is an exchange of information
between the devices, after which the
dispatcher sees the fault location
on the electronic diagram in the
control center. The program provides
solutions to the problem.
The main goal of the ‘smart
grids’ technology is to make the
generation, transmission and
distribution of electric power more
energy efficient and safe.
Smart Grids
Implementation Project
In Astana, at the power supply
for the EXPO-2017 exhibition
complex implemented the smart
grid technologies from Siemens.
The latest technologies provide an
uninterrupted power supply to the
exhibition pavilions and also reduce
energy costs by reducing losses.
It is worth noting that Astana
became the first city in Kazakhstan
to launch a pilot project for the
implementation of smart grids.
Within the framework of the
project, a new dispatch center (DC)
for managing electricity grids was
created. The modern power facility
consolidates the operation of the
grids and performs full monitoring
of the equipment load. At present,
the center is one of the most
innovative and technologically
advanced in Kazakhstan. It has
increased the monitoring of the
power distribution network to 100%
and reduced the risk of personnel
mistakes in operation.
Siemens solutions integrate all the
key elements of the energy supply
of the exhibition complex into a
single intelligent network. For the
first time digital protection relay
devices of the fifth generation
were used, capable not only to
automatically disconnect the
damaged sections, but also transmit
information about the accident to
the dispatcher's console online.
In addition, quality control and
accounting devices have been
introduced that can process data
on energy consumption in the
exhibition facilities as well as check
the quality of electricity coming
from Astana power grids.
In conclusion, it should be noted
that future power grids will be more
effective and safe. The trend in
energy decentralization will cause
the creation of micro grids that will
work using digital technologies,
linking all systems together.
Electricity received from alternative
energy sources will also be actively
used. New technologies will give
an impetus to the growth of
‘smart cities’, capable of providing
residents with comfortable living
conditions and reliable energy
supply, able to withstand natural
disasters.
