Abstract

This paper presents studies carried out on the Hellenic system in order to assess the effect of the existence of only one main interconnection with the rest Balkan system, the Bulgaria interconnection. The dynamic behavior is analyzed for selected disturbances and shows that for large generation loss in the Greek network there is isolation of the Greek system, due to the short activation time of the Bulgaria overload protective device. In this case load shedding is necessary for safety reasons. In general it is concluded that the Greek system remains stable, even in large disturbances
