United Power System of Russia in Brief
3
One of the largest power systems in the world (vs. US and UCTE)
On-going restructuring/unbundling: from vertically integrated
monopoly to liberalized system
Geographical size creates a number of particularities:
Electric power transmisson over very large distances
Ultra-high voltage and high voltage lines
Emergency automation
High degree of interdependence and cooperation within IPS/UPS
due to a former single USSR power system
System control in Russia is deigned based on centralized
dispatch but IPS/UPS synchronous zone is already using
decentralized dispatch

System Operator for UESR
5
Role of the SO:
• Control and Operation of the Unified Energy
System of Russia
• Ensuring the reliability of the national
power system and quality of electricity
supply (no major power system
incidents and improve power quality in
the midst of system restructuring)
•Support for the implemenation and
opertion of the competitive market
The largest mapboard in the world, from the Baltic
Sea to the Pacific Ocean – 7000 km.

Current Chalenges for System Operator

Reform of the dispatch control in Russia:
Significant change in organizational structure
Changes necessary due to development and implementation of power and ancillary
services markets
Reliability/quality:
Increase of the quality of supply maintaining a high power system reliability – main
item: load/frequency control (modernization of primary, secondary regulators; ensuring
necessary active power reserves quality and quantity)
Transition from the centralized planning and control of a single (ex-USSR) power
system to a decentralized one – elaboration and implementation of common operation
rules for all partners of the synchronous zone
Market Support:
Ensure the necessary support to the market oriented reforms of electricity sector due
to a huge role of the System operator in competitive market infrastructure –
Implementation of a modern SCADA/EMS system
Elaboration and implementation of balancing and ancillary services market
Integration with UCTE: Feasibility study of the synchronous interconnection will be
jointly performed by UCTE and UPS/IPS TSO-s (ISO-s)

SCADA/EMS Implementation
Scope of the Project and Current Status
8
All existing SCADA/EMS were designed by Russian companies. Although the
system are still functioning according to specifications SO decided to replace
the SCADA/EMS on all three hierarchical levels with modern state-of-the-art
systems., including:
Central Dispatching System (CDU) in Moscow and 7 territorial systems
(ODU’s)- Center, Northwest, Middle Volga, North Caucasus, Ural, Siberia,
Far East. A supplier for these systems will be selected through
international tender.
55 regional systems will be supplied by domestic companies.
Current Status:
Evaluation of Tenders for CDU and 7 ODUs
Implementation of the 55 regional systems is well under way. Currently
already xxx systems in operation
All systems shall be in operation by the end of 2007

Reasons for Replacement
9
Existing systems are closed to the end of its useful life cycle
New requirements for the support of the competitive Wholesale Energy Market in
Russia
Interfacing with future automation systems of Federal Grid company and Trade
System Operator
Efficient synchronous interconnection with UCTE and coordination with IPS’s of
former USSR republics.
Economical benefit of the system: Net present value for CDU and 7 ODUs is
estimated well above 500 MEuro, due to:
Increased reliability and quality of operational control
Optimal Maintenance Scheduling
Improved Generation Scheduling
Reduced overall network losses

Key Aspects of the Project
10
Turn Key project: All system databases, displays and network
models shall be delivered and implemented by the supplier
CIM and GID Compliance
Advance Generation Scheduling functionality
Market support functions and market interfaces
