Oscillation Behaviour of the Enlarged UCTE Power System Including the Turkish Power System

Abstract

Due to deregulated energy market conditions and the planned extension of the UCTE power system towards Eastern Europe, as well as towards the Middle East and North Africa to close the so called “Mediterranean Ring”, the oscillation damping behaviour of the UCTE power system is gaining more and more in importance. Within the present paper, the oscillation damping behaviour of the enlarged UCTE power system after the synchronous connection with the Turkish power system is analysed, using time and frequency domain methods. Firstly the Turkish power system is analysed as a separate network in isolated operation as the case still is today. Subsequently the enlarged UCTE-system, including the Turkish power system is analysed. Differences in the oscillation behaviours are shown, precarious system constellations are identified and measures to solve occurring problems are given and discussed.
