WHAT IS A SMART GRID?
 It is a next evolutionary step of DISTRIBUTION SYSTEMS evoked by new
requirements – decentralised generation, e-mobility, …, which elicited the
necessity of new functionalities of DS to ensure the implementation of such new
requirements while providing reliable and safe operation of DS …
 This was implemented many years ago through the Control Centre of the
Power System at the level of VHV, HDO [power supply with ripple control] also at
the level of LV
SO WHERE IS A PROBLEM?
 It concerns a system change – not a gradual technology development at the
level of individual components – it requires huge financial sources & long time
 Task definition: what functionalities are meaningful or economically beneficial
in the Czech Republic and in what time – from the perspective of the whole
society and not from the perspective of grid operators
 What is the extent and reasonable schedule of Smart Grid implementation?
CONDITIONS FOR MEANINGFUL
DEVELOPMENT OF SMART GRIDS
 Definition of realistic goals (in the form of service parameters), including the
assessment of impact on power prices for end consumers
 Harmonisation of requirements and options of customers, market
environment, subjects of regulation … and related laws of physics
 Acquirement of know-how and experience
…
 Definition of realistic implementation program – balancing of capacities,
financial funds, agricultural terms, …
 Creation of the national concept of meaningful development of Smart Grids
within the current situation of the Power System of the Czech Republic
SMART GRIDS ARE JUST A VISION ?
 Development of integration of renewable
sources in the Czech Republic

PILOT PROJECT OF SMART METERING - AMM
Situation of smart meter implementation in CZ
Initial situation in the Czech Republic differs from other EU countries in many aspects :
 Remote reading of 60 % of all power consumption is in use at 38,000 industrial power
consumers equipped with so called “continuous” electricity meters [meters with
averaging of respective power output within a specified metering interval; data are
transferred automatically]
 HDO system [power supply with ripple control] is widely in use in the Czech Republic
since 1980-ties
 HDO system serves for daily load diagram balancing - by shaving power consumption
peaks; this system has been implemented by ČEZ Distribution for its 1.1 million
household power consumers
 This system is in use for those consumers which utilise power for heating and hot
service water preparation – various preferential [low] tariffs are available for such
consumers
 Quality and reliability parameters of power distribution grid are at high-standard level
What are the goals of AMM pilot project
The purpose of AMM pilot project is to test a new technology in a real environment and to get
answers to the following questions:
 Smart meters: how will they be accepted by customers?
 What is the potential of customer behaviour change?
 Newly offered products and services: how will they be accepted by customers?
 Possible total implementation of AMM in CZ: what will be its impact on logistics and
processes?
 What are the real benefits and costs of complete solution?
 What implemental, operational or safety risks can emerge?
 Can we get real and credible data or information for future decisions?
PILOT PROJECT SMART REGION
Why a Smart Region at Vrchlabí?
 Adequate size and extent of the region for the
pilot project purpose
 Possibilities to include several co-gen plants and
potentially also some small hydro power plants
 With its close distance to Krkonoše Natural Park
and stress on environment conservation, Region
Vrchlabí is ideal for the concept of e-mobility
 Synergic effect of high voltage level unification
(change from 10 → 35 kV)
 Helpfulness of Municipal Council and Mayor
of Vrchlabí
 Potential to include local industry (Teplo
Krkonoše [a heating provider], nkt cables)

CONCLUSION
To cope with future (not virtual) reality, it is necessary to maintain visions sufficiently ahead of
time and set real expectations adequately.
 Smart grids are not only a technological layer – they should be perceived as new
functionalities / services at the level of whole society
 It is the task of society to define a meaningful and economically viable scenario of
development
 It is the system matter – it is necessary to keep the dialogue of all participating players
 Even when having a very conservative view on the matter, it is necessary to start
concept activities TODAY
