| چکیده | ||
| This study addresses the urgent energy challenges associated with climate change, exacerbated by industrialization and rapid population growth, through the simulation of a renewable energy system at Amirkabir University. Using Design Builder, we assessed the energy demands for electricity, cooling, and heating in a faculty building, and subsequently developed a combined generation and multi-storage system in HOMER that integrates renewable energy sources, natural gas, and advanced storage solutions, including hydrogen and batteries. Our analysis compares the performance of systems utilizing 1 kW and 10 kW wind turbines, demonstrating that the 10 kW turbine significantly outperforms its smaller counterpart. Solar energy contributes 1,931,801 kWh (89%) to the system, while wind energy accounts for 216,261 kWh (10%). The economic evaluation reveals a total present cost of $6.77 million for the system with the 10 kW turbine, yielding a production cost of $0.377 per kWh and reducing CO2 emissions to 102,586 kg/year. Furthermore, sensitivity analysis indicates increased wind energy production under higher wind speeds, validating the potential for wind energy in Tehran. Overall, this research highlights the effectiveness of integrated renewable energy systems in mitigating greenhouse gas emissions and meeting rising energy demands over a projected 20-year lifespan while demonstrating significant economic viability. | ||
