In order to develop an eco-friendly island, it is necessary to make electricity, heat and water independence using renewable energy as an energy source.
Out of multiple HRES solutions, two systems were declared as the optimal solutions based on lowest net present cost (NPC) and lowest levelized cost of energy (LCOE). Second case study deals with the techno-economic optimization of HRES designed for fulfilling yearly electricity consumption of Deokjeokdo island. In first case study the performance of a small HRES, consisting of photovoltaic (PV) panels and wind turbines installed at Deokjeokdo island in South Korea, has been analyzed using real time measured experimental data. Furthermore, two case studies of HRES have also been included to demonstrate the practical working of such energy systems. Present study includes the basic information about the working methodology and other characteristics of HRES. The main application of such energy systems is to provide electricity to remote areas such as villages and islands, where no other means of power generation are available. Hybrid renewable energy system (HRES) consists of more than one type of renewable energy technology such as wind and solar.
