Titel der Reihe: Feasibility Aspects of a Synchronous Coupling of the IPS/UPS with the UCTE


At the beginning of 2002, the Electric Power Council of the Commonwealth of Independent States (EPC CIS) expressed its interest in a synchronous interconnection with the power systems of the CIS countries and the Baltic States (IPS/UPS) to the power systems of the members of the Union for the Co-ordination of Transmission of Electricity1 (UCTE). After UCTE completed a Pre-feasibility Study [1] analysing the steady state load-flow in 2003, the UCTE and the EPC CIS's Commission on Operational and Technological Coordination (COTC) agreed to launch a detailed feasibility study on the synchronous interconnection of the power systems concerned. The project was carried out in close co-operation by a UCTE consortium and a group of companies from the IPS/UPS between 2005 and 2008. The Feasibility Study was designed to answer three major questions: • Is a synchronous interconnection of the IPS/UPS and the UCTE possible? • What measures have to be taken in both systems? • What are the associated costs? Extensive investigations of the systems were carried out dealing with steady state analysis, system dynamics, power system control, operation and organisation as well as the analysis of legal framework. The system simulations confirmed the necessity of the transmission network re-enforcements mainly dedicated to the IPS/UPS interface area. Further, a higher potential risk for the dynamic stability of the interconnected systems compared to the current performance of both systems had been identified. Additionally, further efforts for the adaptation and harmonisation of existing defence and restoration plans in both synchronous areas would be necessary. Besides these technical issues, the need for interzonal, bilateral and multilateral agreements is substantial in order to setup a legal basis for a future reliable market platform with the focus on necessary organisational and operational issues under the framework of EU-market requirements and standards. The investigations point out that even if a synchronous coupling appears viable, it must be considered as a long-term option. The study results underline the overall complexity of a synchronous coupling first in the context of system security and reliability but also from the point of view of operability of the underlying electricity markets. Additionally, the study considers the evidence of non-synchronous system coupling possibilities by high voltage direct current (HVDC) technology, e.g. by back-to-back links. This worldwide used technique in large transmission systems may result beside its technical and economic advantages in a more cost-effective and thus "easier to realise" perspective for merging the electricity systems. At the end of 2008 the project partners worked out a documentation of the study results. The "Summary of Investigations and Conclusions", endorsed by the study partners, is available at www.ucte-ipsups.org.
