Feasibility Study: Synchronous Interconnection
of the
Power Systems of IPS/UPS with UCTE
Project Profile
From the beginning...
In 2002 UCTE1 received a request from RAO UES Russia acting on
behalf of EPC CIS2 and the Baltic States for a synchronous interconnection
of the IPS/UPS3 power systems with UCTE. After the completion of
a pre-feasibility study in 2003 dealing with steady state system
analysis, UCTE decided to launch a broad feasibility study in
order to answer the three main questions:
- Is a synchronous interconnection of IPS/UPS and UCTE possible?
- What measures have to be taken on both sides?
- What are the associated costs?
The results of the three years project will be used as a basis
for further decisions on system extension on both sides.
The challenge: one “heart beat”
from Lisbon to Vladivostok
The feasibility study is another milestone in the history of
UCTE: the interconnection would finally lead to synchronously interconnected
power systems with a total installed capacity of 800 GW spanning
13 time zones and serving about 800 million customers. Presently,
there is no existing example in the world which operates in synchronous
mode in this extension.
The study will be performed as a joint project under the responsibility
of UCTE. More than 100 experts from both sides are involved in
the project. This huge amount of personnel resources is an attribute
not only to the size of the system to be investigated, but also
to the broad aspects of the tasks to be fulfilled: each of the
two synchronous systems has been developed independently in technical,
organizational and legal terms in the past. The overall project
budget amounts to approximately 10 Million €.
Organisation and time frame
The UCTE-Consortium responsible for the project consists of 11
TSOs from 9 countries, namely: E.ON Netz GmbH (Germany), ELIA
System Operator S.A. (Belgium), MAVIR Hungarian Power System Operator
Company (Hungary), Natsionalna Elektricheska Kompanbia EAD (Bulgaria),
PSE-Operator S.A. (Poland), Red Electrica de Espana S.A. (Spain),
Reseau de Transport d'Electricite (France), RWE Transportnetz
Strom GmbH (Germany), Slovenska elektrizacna prenosova sustava,
a.s. (Slovak Republic), National Power Grid Company “Transelectrica”
(Romania) and Vattenfall Europe Transmission GmbH (Germany).
On IPS/UPS-side a group of 7 companies have established a joint
agreement for the project: Belenergo (Belarus), Eesti Energia
(Estonia), Latvenergo (Latvia), Lietuvos Energia AB (Lithuania),
Ukrenergo (Ukraine), Moldelectrica (Moldova) and System Operator
- Central Dispatch Organisation of Unified Energy System of Russia
(RAO UES) which has the leading role for the Eastern partners.
General project organization:
a joint structure from the working to the Board level
On the working level five working groups deal with the subtasks
steady state analysis, system dynamics, power system control,
operational and organizational issues and legal aspects. All internal
and external activities are coordinated by the project management.
Further project entities are:
- a Project Representative Board, which accompanies the project
on the political level with representatives from the European
Parliament, European Commission, UCTE, Baltic States and CIS
countries
- a Project Management Board, which is responsible for steering
the project and deciding of further steps as well as of approving
of reports. This joint board consists of representatives from
UCTE and IPS/UPS.
The total project duration of three years – until April
2008 – is globally divided into several main phases such
as data collection and modeling, system simulation and verifying
and summarizing of results.
The working schedule:
an ambitious time frame
for the challenging investigations
In early 2004 a Cooperation Agreement between the UCTE-Consortium
and the IPS/UPS companies has been prepared. The agreement defines -
on a legal basis - the overall framework of the cooperation between
both parties. The Cooperation Agreement was signed during the project
kick-off on 19-20 April 2005 in Brussels.
