Abstract

Within the last 20 years, the electricity system developed from serving local independently working countries to a highly intermeshed system with powerful transmission lines. The original idea of the interconnected system was to share expensive reserve energy to use system synergies. Some countries used this possibility to trade cheap energy to enlarge the turnover and efficiency of the system. Nowadays the UCTE (1) frequency synchronous zone covers whole central Europe and some Eastern European countries.
In 2002 Russia requested to connect to the UCTE system in order to build the largest frequency synchronous zone worldwide. The following work investigates the influence of a possible integration through a simplified mathematical equivalent. Subsequent evaluations of the interconnected system focus on the operation of a reliable and safe electric power system.
In order to find influence parameters disturbing the balance of the system and leading to emergency situations and blackouts, the development of three major blackouts (Swedish, Italian and Hellenic) are analyzed. Selected power flow scenarios are analysed in terms of the essential factors (congestions, co-ordination problems) for a reliable and safe operation of the today's and future synchronous zone. The enlargement of the system is supposed to have a positive influence on system stability and reduce the number of major blackouts.
