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.
