Investigation of necessary transmission enforcements at the Balkan region of ENTSO/E in the sense of inter-area oscillations after interconnection of Turkey

This paper presents the investigation of 10-Year Network Development Plan (TYNDP) of ENTSO/E CESA countries for the planning period between 2010-2020, concentrating on transmission enforcement needs pointed for the Balkan region. The correlation between those transmission enforcements and the growing oscillations on the weak tie-lines of the Balkan countries particularly after the interconnection of Turkey with the ENTSO/E is discussed. The complaints of the Balkan countries due to growing power oscillations are also discussed considering the tie-line enforcement needs emphasized in the TYNDP report. The sufficiency of current tie-lines between Turkey and ENTSO/E is analyzed in the sense of inter-area oscillations based on computer simulations.
