Title - Supplying not electrified island with 100% renewable energy based micro grids:

A combined approach of geospatial analysis and energy system modelling was applied on a global scale to study the feasibility of RE integration into island grids [19] and for a classification regarding the RE potential on islands [20] but not specifically for the strategic planning of providing energy access. [...] Our approach builds up on available information on grid extension and location of power plants: A geospatial dataset of the island contour for the entire Philippines provided by the National Mapping and Resource Information Authority of the Philippines (NAMRIA) serves as base map and provides information on the spatial extent of single islands [41]. [...] In contrast to the k-means approach the cluster assignment per data point is based on the dissimilarity to the medoid and not the mean value of a cluster. [...] The case study for cluster 2 is located north of Palawan in the western part of the Philippines and the case study of cluster 4 is found in the Sulu Sea in the most southern part of the country. [...] The reliability of the 100% RE systems comes at a considerable price: Since the energy system components are dimensioned to supply the demand even in the worst-case- scenario of the year (low RE resources and high demand) the power capacities are oversized compared to the typical daily electricity demand.
