Abstract

The current research was conducted with the aim of technical, economic and environmental feasibility of a small-scale solar power plant in the northwestern region of Iran. The area studied in the current research is the northwestern region of the country. The research is applied in terms of its purpose and the current research is descriptive or non-experimental and in terms of data type, it is quantitative. In this research, firstly, the study area will be studied by field and library methods, and then the amount of energy and capacity factor of the power plant will be calculated by analytical method, and then, the economic aspect of the project will be investigated. In this research, using the RETScreen software, the amount of solar energy received, the power plant's capacity factor, the estimation of initial and periodic costs, the calculation of the amount of greenhouse gas reduction and the financial evaluation will be discussed. The results show that the highest amount of sunlight in Tabriz city is in June and the lowest amount of sunlight throughout the year is in December. In the 10,000 kW solar power plant selected by setting the benchmark, it can be said that, at the minimum cost, the production of each kilowatt hour of electrical energy in Tabriz city through solar energy costs 0.275 dollars and it costs a lot compared to other methods. assigns Producing the same amount of electricity through a photovoltaic system costs $0.060. According to the obtained results, if this power plant is set up, it is not economical, but it will significantly reduce air pollution.

نیروگاه خورشیدی یکی از فناوری­های در حال توسعه در زمینه تولید انرژی الکتریکی با کاهش آلودگی زیست محیطی است. باتوجه به اینکه ایران از پتانسیل خوبی در زمینه انرژی خورشیدی برخوردار است، استفاده از این منبع خدادادی و نامحدود ضروری بنظر می­رسد. پژوهش حاضر با هدف امکان سنجی فنی، اقتصادی و زیست محیطی نیروگاه خورشیدی مقیاس بزرگ در منطقه شمالغرب ایران انجام شده است. منطقه مورد مطالعه در تحقیق حاضر استان آذربایجان­شرقی و شهرهای اطراف این استان در استانهای همجوار می‌باشد. تحقیق از نظر هدف کاربردی و از نوع توصیفی، غیرآزمایشی می‌باشد و از منظر نوع داده، کمی می‌باشد. در این پژوهش ابتدا به روش کتابخانه‌ای به مطالعه منطقه مورد مطالعه پرداخته است و سپس به روش تحلیلی به محاسبه میزان تولید انرژی و ضریب تبدیل انرژی نیروگاه پرداخته شده و در ادامه، جنبه اقتصادی و زیست محیطی طرح مورد بررسی قرار گرفته است. در این تحقیق با استفاده از نرم افزار RETScreen به محاسبه میزان انرژی خورشیدی دریافتی، ضریب ظرفیت نیروگاه، برآورد هزینه های اولیه و دوره­ای، محاسبه میزان کاهش گازهای گلخانه ای و ارزیابی مالی پرداخته شده است که نشان می­دهد شهر تبریز نسبت به 9 شهر دیگر ضریب تبدیل انرژی بالاتری دارد واین شهر برای احداث نیروگاه فتوولتائیک انتخاب می­گردد. نکته قابل توجه اینست که، در نیروگاه 2 مگاواتی، درآمد حاصل از3 سال اول، به تنهایی می­تواند هزینه سرمایه گذاری اولیه نیروگاه رابازگرداند و این بازگشت سرمایه برای نیروگاه 100 مگاواتی 7/3 سال می­باشد. درآمد سال اول برای نیروگاههای 2 و 100 مگاواتی بترتیب 275625دلارو 12330576دلار محاسبه شده است که نشان میدهد این طرح توجیه اقتصادی دارد و علاوه بر این موضوع،  احداث نیروگاه خورشیدی به عنوان یک منبع انرژی پاک می­تواند منجر به عدم انتشارco2    و کاهش مصرف آب جهت تولید انرژی شود و از نظر زیست محیطی بهینه و توجیه پذیر است.
