In this thesis, a feasibility study for the design and optimization of an Energy system will be conducted. Hybrid Renewable Energy Systems (HRES) are an necessary option for the energy supply in distant places, such as in this case islands, where grid expansion is challenging. In this thesis, ten different scenarios will be examined, ranging from hybrid Power Stations with Low-Renewable energy(RES) source fractions andnew generators to systems depending entirely on RES. The case study of the Dodecanese Island Symi, which is not presently linked to the grid, was chosen. This study's system will be sized depending on the year 2021. The system has a load of 14,218 MWh (peak load of 3,950 kW) and is not presently linked to the power grid of mainland Greece. The research will assume the project's lifespan to be around ten years, since Symi island is expected to be connected to the main grid by 2030 under IPTO plans. The optimization issue will consider Europe's present economic state, market pricing, and maintenance and operational costs. All parameters will be imported into HOMER PRO (student version with License Id: 180241), and each scenario will be evaluated based on the Net Present Cost (NPC), cost of energy, and minimum Excess Electricity %.
