In this thesis the installation of a hybrid power generation system in Astypalaia is examined, as in remote areas such as some islands the extension of the national grid starting from the mainland is considered economically unviable. A hybrid power system combines renewable energy sources with conventional sources and battery storage to produce energy on or off the grid. First, the theoretical background required to establish a hybrid power system is analyzed and then the techno-economic analysis for the design and optimization of the corresponding proposed system for the island is carried out. In this study we will consider different scenarios of RES penetration in the hybrid project from low penetration to full penetration and meeting all the needs of the island. The selection of the optimal system configuration is done using Homer software, which ranks all possible configurations that meet the specifications based on economic criteria. The evaluation of each scenario will be based on Net Present Cost and minimum excess electricity.
