Summary

The purpose of the work is the study of the construction and operation of an autonomous hybrid system for the production and storage of electricity on the island of Astypalea. The objective of the work is to evaluate the advantages of the hybrid technology, as well as the effect of the station on the energy security and sustainability of the island. In particular, the thesis will examine (a) the technology and design of the hybrid station, (b) the effect of the station on the energy security of the island, (c) the techno-economic evaluation of the station in the energy sufficiency of the island.Energy storage: The system will include energy storage units with a total capacity of 10 MWh.The study conducted to evaluate the system showed that the system will have the following benefits:Reduction of dependence on conventional fuels: The system will help to reduce Astypalaia's dependence on conventional fuels, such as oil, which is the main fuel for the operation of diesel units in the current situation.Reduction of production costs from conventional fuels: The system will help to reduce the production costs of Astypalea for the operation of the diesel units which, based on RAE's data, is particularly high. This will result in a reduction in the cost of electricity production and an increase in the island's energy security.Increase in energy security: The system will increase the island's energy security, as it will be able to provide a continuous supply of electricity, even in periods of low production from renewable energy sources.Overall, the study showed that the stand-alone hybrid electricity generation and storage system in Astypalaia is a viable project that will bring significant benefits to the island. At the same time, the existing plan is implemented on the basis of the correct dimensioning, providing a facility that can cover the basic energy needs of the island with a relatively low capital cost, while at the same time being a sustainable financial investment.Initially, an analysis of the literature took place, with the presentation of the existing situation at regulatory level in the energy sector both at European and Greek level. Special reference was made to the adoption of the most recent legislation at the European level, as a result of the geopolitical and economic crisis that Europe has been experiencing in recent months. At the same time, an analysis is made for the individual production and storage technologies that are the subject of the present study. A brief reference to generation technologies from wind, photovoltaic as well as storage units is provided as part of the literature review. Then, the reference to the autonomous hybrid electricity production and storage systems in operation (or under construction) in Greece.With the analysis of the systems, the transition is made to the basic examination scenario of the present study, which is the autonomous hybrid system of electricity generation and storage in Astypalaia. Initially, the available metrological data as well as the data for the operation of the energy network as available from RAE and DEDDIE are provided in detail. The following technologies are considered as an object of consideration (basic information is provided as well as a production simulation model for the RES generation units) for the autonomous hybrid electricity generation and storage system in Astypalaia:Solar energy: The system includes solar panels with a total power of up to 7 MW.Wind energy: The system will include wind turbines with a total power of 1,5 MW. As stated in the study, the assessment of wind potential is at a theoretical level given the technical limitations that preclude the installation of wind potential on the island.
