“…In Turkey, two distinct studies tackled hybrid energy system analysis using HOMER Pro, integrating photovoltaic panels, wind turbines, biogas generators, and diesel generators [14], and an optimization of a grid-connected photovoltaic-based energy system using data from the Meteorological General Directorate, NASA, and PVGIS. The latter indicated a significant reduction in environmental pollutants with an annual average solar energy production of 160,000 kWh [15]. This broad spectrum of studies demonstrates global interest in the analysis and optimization of hybrid energy systems, showcasing various methods and tools in the field.…”

Facing the global increase in population, escalating energy demands, environmental impacts of internal combustion engines, and potential depletion of fossil fuels, the urgency of developing renewable energy systems becomes more evident. This study takes place during a period of rapid electric vehicle adoption and escalating demand for renewable energy. It presents optimization and comparative analysis of hybrid and off-grid charging stations across six distinct regions. The process of establishing off-grid hybrid charging stations in each region is critically analyzed, using the HOMER program to determine the most efficient placement. HOMER, an optimization tool for renewable energy systems, enables lifecycle cost analysis. This method not only strengthens our energy independence but also supports the economy and reduces carbon emissions, positively impacting the environment. Comparative optimization analysis, based on technical and economic metrics across the provinces, identifies Manisa as the optimal location for the planned electric vehicle charging station. The station is expected to generate a total energy of 3,049,337 kWh per year, with a Net Present Value of 7.24 M$, a Levelized Cost of Energy of $0.441 per kWh, an annual operation cost of $175,795, and an initial capital cost of 3.69 M$. In conclusion, this study aims to improve environmental outcomes and contribute positively to the economy by reducing reliance on fossil fuels and fostering a quick transition to renewable energy.

In response to technological advances, environmental concerns, and the depletion of conventional energy sources, the world is increasingly focusing on renewable energy sources (RES) as a means of generating electricity in a more sustainable and environmentally friendly manner. Türkiye, with its advantageous geographical location, long hours of sunshine, and favourable climatic conditions, has a high potential for the use of solar energy. The objective of this study was to identify an energy system that minimizes investment costs while optimizing the levelized cost of energy (LCOE) and minimizing greenhouse-gas (GHG) and carbon dioxide emissions. To achieve this, the study used the concept of nanogrids (NGs) and carried out different evaluations for electric vehicle charging stations (EVCS) at different energy levels connected to the grid. The research focused on classic apartment buildings and multistory condominium-style buildings in Istanbul, Türkiye. Using HOMER Grid 1.11.1 version software, the study identified two optimal configurations: a PV–GRID system with 7 kW photovoltaic capacity and a PV–WT–GRID system with 90 kW PV capacity and 6 kW wind-turbine capacity. These configurations had a significantly lower LCOE compared to the cost of electricity from the conventional grid. When examining the sensitivity to economic factors, it was observed that the net present cost (NPC) and LCOE values fluctuated with electricity prices, inflation rates, and equipment costs. In particular, the two optimal configurations did not include a battery energy-storage system (BESS) due to the low energy demand in the PV–GRID system and the efficiency of the wind turbines in the PV–WT–GRID system. This highlights the need to tailor energy solutions to specific consumption patterns and resource types. In conclusion, the adoption of PV–GRID and PV–WT–GRID systems in Istanbul’s urban buildings demonstrates economic viability and environmental benefits, highlighting the importance of renewable energy sources, particularly solar PV, in mitigating energy-related environmental challenges, such as reducing CO2 emissions and reducing dependence on conventional grid electricity.
