Strategic changes in the
electricity grids management

Current situation in CR
Directive 2009/72/EC:
•
Smart Metering Systems to be implemented at 80 % end users
by 2020
key step of SG implementation according to EU
Ambitious goals of EU 20-20-20 by 2020:
•
Increase share of RES in EU to 20 %
•
Increase energy efficiency in EU by 20 %
•
Decrease emissions of GHG by 20 %
Closely related not only to each other but also to the SG
concept
Key step of SG implementation in CR?

Results of the set goals of EU
Enormous policy of RES and CHP support:
•
Great amount of small non-predictable RES in the distribution grid
•
vertical vs. horizontal electricity flows → requirements on the
distribution grid it was not designed to
•
Problems with grids management caused by the extensive
wind parks in Northern Europe transfer from transmission grids
to distribution grids

Distribution of installed power in CR by 31.12.2011 [%]
VE – hydro-electric PPT
PVE – pump storage PPT
JE – nuclear PPT
PE – coal PPT
PSE – gas PPT
FVE – photovoltaic PPT
VTE – wind PPT

Key problems in CR
Problems in distribution grids become more serious
→ some of the distribution lines are operated near its transmission limits
Balancing market of regulating electricity
•
Maintenance of balance between electricity production and consumption
at every moment
•
As a result of non-predictable RES the amount of traded regulating
electricity multiplies

Experiences from other countries
Main reasons of smart metering systems implementation:
•
Absence of the system of electricity consumption management
•
High ratio of non-technical losses
•
And others that do not apply to CR

Potential of SG implementation in CR
• implement smart elements for real time control into distribution grids
• optimize production in decentralized electricity sources
• through electricity consumption management and other smart elements
optimize consumption
→ electricity used as close as possible to the decentralized production
• minimize electricity flows in distribution grids
• avoid extensive strenghtening of distribution grids
Smart Metering Systems → global trend of their implementation
• postpone it in CR as long as potential gains do not exceed their costs
• massive implementation→ decrease of related costs
In CR last step of SG implementation

Role of electricity trade
• balance of electricity production and consumption in portfolio
→ the value of electricity changes upon the size and direction of deviation
• trading on Intraday Market
→ saving of deviation costs
