Problematic Integration of Fatal Renewable Energy Systems in Island Grids

Abstract

The islands are often not or partially connected to continental networks and manage their own energy supplies in reaching alone the supply/demand balance and in assuring the quality of the delivered electricity. The low consumption and the lack of interconnections induce energy costs higher than in other regions. The islands are good locations for using new technologies of energy production and storage. For increasing their security, they often prefer to use indigenous sources as renewable ones but the intermittence and stochastic character of these “fatal” energy sources make them more difficult to control and manage and more again in small island networks. Most islands have good renewable energy (RE) resources which are underused in comparison with their real potential. A particular attention is paid to the problem induced by the renewable energy sources (RES) utilization in an island electrical grid on the electrical management.
