Interconnection of solar powered mini-grids - a case study for Kythnos Island
Abstract
The introduction of a substantial penetration from renewable energy sources in the power mix of the Greek islands grids is of great importance. This fact is justified because the island grids are autonomous and are mainly fed by diesel generators, that increase dramatically the energy production cost. Although the wind and solar potential in these areas is excellent, the strong seasonal demand fluctuations as well as the technical minimum restrictions of the thermal stations, pose a barrier. The implementation of a hybrid system with battery storage and an intelligent management system in Kythnos island, are considered to be an effective solution to this problem. The scope of this paper is to examine some grid impact issues for two case studies involving the increase of renewable energy source penetration in the grid of this island.
