The aim of the present dissertation is to assess selected combinatorial desalination systems powered by Renewable Energy Sources (topologies), in order to choose the appropriate one taking into account specific criteria. The results may help decision-makers to take the right decisions to solve the water deficiency problem in arid regions in the Aegean. At first, the desalination technologies are presented, these are thermal and membrane methods. The most widespread method all over the world is reverse osmosis, which exists in Greece too. Desalination process requires great amount of energy. The conventional methods of energy production are considered to be costly and to have detrimental effects on the environment. For this reason, the characteristics of the Renewable Energy Sources are mentioned and how they can function by giving power to the desalination technologies. Decision making in energy sector can be supported by multi-criteria methods. Subsequently, the reasons that multi-criteria methods are used in such kind of decisions are presented. The most widely used methods get analyzed extensively. Then, a review about published works that have to do with application of multi-criteria methods in energy planning is presented. Then, the evaluation process of five specific topologies for Hydra and Donousa islands is reported. Two methods are used, AHP and Promethee method, for each island, in order to have more substantiated results. For Hydra island, we take into account that the environmental criteria are of high weight and for Donousa island, the economical. The results point to the PV arrey through the reverse osmosis plant via voltage buck converter for Hydra and the hybrid system, wind turbines, PV arrey and batteries for Donousa as appropriate technologies for installation on each island. Finally, the data get analyzed and sensitivity analysis is performed in order to note potential transitions in the results, if the criteria weights’ change. keywords : desalination, reverse osmosis, topologies, multi-criteria analysis, renewable energy sources.
