Security assessment of an autonomous system with increased wind penetration and pumped storage hybrid plants

This paper deals with the impact of the integration of hybrid power plants to the secure operation of an autonomous power system with high penetration of Renewable Energy Sources (RES). The hybrid plants considered consist of wind farms and hydro generators with pumped storage units. The analysis is performed for the autonomous power system of Crete, which has already reached saturation level for wind farms without energy storage.
