Abstract :
The scope of this paper is to investigate the interconnection of the autonomous power system of Crete with the mainland power system of Greece focusing on its effects to the dynamic stability of the island. It is assumed here that a Voltage Source Converters high Voltage Direct Current (VSC - hVDC) technology is adopted for the interconnection. The power system is modeled using the DigSilent PowerFactory software package. The power system of Crete is modelled for a number of representative scenarios regarding load demand, renewable energy sources penetration and conventional generation loading. These scenarios are simulated under the presence of critical disturbances both in interconnected and autonomous operation in order to assess frequency and voltage stability. The results are compared in order to evaluate the effect of the hDVC interconnection and conclusions are drawn regarding the technical viability of the project.
