Main mission of UCTE

Providing pre-conditions for a functioning electricity market:

Technical and operational co-ordination in the

synchronous area

Controlling the short-term security of the system with

regard of load, frequency control and system stability

Monitoring the medium to long-term adequacy

between generation and load (3, 5, 10 years)

Responsibility for the development of the synchronous

area

UCTE-IPS/UPS Study – three major questions to answer

Is a full synchronous interconnection of IPS/UPS with UCTE

feasible?

What are the mandatory measures and requirements on both

sides?

What are the associated costs?

Considering technical, operational, organizational and legal

issues the study will answer the following questions:

Additionally, market aspects and environmental issues are

building the conditional framework

Initial priority: maintaining the present performance of the

systems with respect to system security and reliability


Consideration of non-synchronous link projects

• In October 2005 IPS/UPS has taken an initiative to consider non-

synchronous link projects in the investigation.

• Generally, the proposal is supported by the UCTE-Consortium if

projects can be identified with a certain degree of realisation capability

at time horizons to be analysed.

• Nevertheless, in order to identify a possible extension on the amount

of work, data provision and the time schedule, IPS/UPS companies are

requested to provide a description and specification of relevant

projects.

• Based on this information the parties will consult about the next

further steps and try to find a solution to the benefit of the project.

The technical challenge: simulation of two synchronous

systems …

…with different

• geographical extensions

• generation and network structures

• operation philosophies

?


• First common working activities confirm the dimension of the project

and its ambitious time schedule.

• IPS/UPS data provision and the installation of the Wide Area

Measurement System (WAMS) in the whole IPS/UPS synchronous area

have been recognized as pre-requisites for the preparation and

verification of well-qualified simulation models.

• The consideration of non-synchronous link projects will be analysed

after realistic projects are proposed and specified.

• System simulations will be carried out under the initial priority to

maintain system security and reliability on both sides.
