Smart and Sustainable Insular Electricity Grids Under Large-Scale Renewable Integration

Executive Summary: A large share of the recent renewable energy sources (RES) installed capacity has already taken place in insular electricity grids, since these regions are preferable due to their high RES potential. However, the increasing share of RES in the generation mix of insular power systems presents a big challenge in the efficient management of the insular distribution networks, mainly due to the limited predictability and the high variability of renewable generation, features that make RES plants non-dispatchable, in conjunction with the relevant small size of these networks. In parallel, the Smart Grid initiative, integrating advanced sensing technologies, intelligent control methods and bi-directional communications into the contemporary
