Abstract :

Introduction: Renewable energy is one of the vital components in reducing carbon emissions and mitigating climate change. The use of renewable energy sources such as solar, wind, hydro, biomass, and geothermal provides energy without greenhouse gas effects on the planet. This study examines the efficiency solar-wind hybrid power plant on the 30th parallel north was studied by simulating energy production in the form of three power generation designs with a nominal capacity of 7 MWh from the solar-wind hybrid power plant in four cities of Cairo, Houston, Chongqing, and Shiraz. The study was conducted using PVsyst, SAM, and Transys software. Materials and Methods: By simulating and analyzing the following three proposed plans in each city and comparing them, it is possible to reach the most efficient range of the power distribution ratio of the combined solar-wind power plant. First plan) 25% of the total power of the power plant is from solar energy and 75% of the total power of the power plant is from wind energy. Second plan) 50% of the total power of the power plant is from solar energy and 50% of the total power of the power plant is from wind energy. Third plan) 75% of the total power of the power plant is from solar energy and 25% of the total power of the power plant is from wind energy. By examining the amount of annual energy injected into the network, the amount and effect of using renewable resources in reducing carbon gas production is analyzed and calculated. Results and Discussion: In addition to providing energy, the combined power plant will increase the reliability factor and preserve non-renewable resources and reduce greenhouse gases. All three software can be used in power plant simulation and analysis and the results are in good agreement. Conclusion: The first design is approximately 30% more efficient than the second design and 85% more than the third design. Shiraz with the production of 48466 megawatts per year reduced carbon dioxide emissions by 23651.408 tons, in Cairo with the production of 45799 megawatts per year the carbon dioxide emissions decreased by 25189.45 tons, Houston with the production of 40979 megawatts per year reduced the carbon dioxide emissions by 15203.209 tons.
