چکیده

با توجه به نیاز روزافزون انرژی و پدیدۀ گرمایش جهانی که نتیجۀ آن تغییرات آب‌و‌هوایی است، لزوم استفاده از انرژی‏های تجدیدپذیر امری انکارناپذیر است. از میان انرژی‏های تجدیدپذیر، خورشید به دلایل زیادی از جمله دسترسی آسان و سهولت تبدیل شدن به انرژی الکتریکی اهمیت قابل توجهی دارد. ﺍﯾﻦ ﻣﻄﺎﻟﻌﻪ ﻃﺮﺍﺣﯽ، ﺗﺤﻠﯿﻞ ﻋﻤﻠﮑﺮﺩ ﻭ ﺑﻬﯿﻨﻪ‌ﺳﺎﺯﯼ ﯾﮏ ﺭﯾﺰﺷﺒﮑۀ ﺗﺮﮐﯿﺒﯽ ﺭﺍ ﺑﺮﺍﯼ ﻣﺠﺘﻤﻊ دانشگاهی ﻭﺍﻗﻊ ﺩﺭ شهر همدان (دانشگاه صنعتی همدان) ﺑﺎ ﺍﺳﺘﻔﺎﺩﻩﺍﺯ ﻧﺮﻡ‌ﺍﻓﺰﺍﺭ ﺑﻬﯿﻨﻪ‌ﺳﺎﺯﯼ ﻣﻨﺎﺑﻊ ﺍﻧﺮﮊﯼ ﭼﻨﺪﮔﺎﻧﻪ (HOMER) ﺍﺭﺍئه ﻣﯽ‌ﮐﻨﺪ. ﺩﺭ ﻃﺮﺍﺣﯽ ﺭﯾﺰﺷﺒﮑۀ یادشده پنلﻫﺎﯼ ﻓﺘﻮﻭﻟﺘﺎئیک، توربین بادی، دیزل ژنراتور، ﺑﺎﺗﺮﯼ، ﻣﺒﺪﻝ ﻭ ﺑﺎﺭﻫﺎ ﺑﻪ ﻋﻨﻮﺍﻥ ﯾﮏ ﺳﯿﺴﺘﻢ ترکیبی ﻣﺘﺼﻞ و منفصل از ﺷﺒﮑﻪ ﭘﯿﮑﺮﺑﻨﺪﯼ ﺷﺪﻩ‏اند، هزینه‏ها‏ی مربوطه به صورت جهانی و عمر ریزشبکه 20 سال در نظر گرفته شده است. ﻧﺘﺎﯾﺞ ﺷﺒﯿﻪ‌ﺳﺎﺯﯼ ﻧﺸﺎﻥ می‏دهد در سناریو اول با بهره‌برداری از 50کیلووات انرژی خورشیدی و 15کیلووات انرژی بادی میزان خرید انرژی از شبکۀ برق سراسری به میزان 117021 کیلووات ساعت در سال تقلیل می‏یابد که کاهش هزینۀ برق مصرفی و انتشار دی‌اکسید کربن به مقدار 71153 کیلوگرم در سال را به همراه دارد. همچنین، از مصرف بیش از سقف قرارداد خرید برق که اعمال جریمه را به همراه دارد جلوگیری می‌کند. در سناریو دوم مشخص ﺷﺪ ﮐﻪ ﺳﯿﺴﺘﻢ ﺭﯾﺰﺷﺒﮑۀ ترکیبی ﭘﯿﺸﻨﻬﺎﺩﯼ ﺗﻘﺎﺿﺎﯼ ﺍﻧﺮﮊﯼ دانشگاه ﺭﺍ به صورت پایدار و منفصل از شبکۀ برق سراسری ﺗأﻣﯿﻦ می‌کند، ریزشبکۀ یادشده با 63/27 درصد ضریب نفوذ انرژی‌های تجدید‌پذیر ﺑﻪ ﻣﻔﻬﻮﻡ ﭘﺮﺩﯾﺲ ﭘﺎﮎ ﮐﻤﮏ می‌کند.

چکیده [English]

Due to the increasing need for energy and the global warming phenomenon resulting from climate change, the increasing need to use renewable energies is undeniable. Among renewable energies, solar energy is the most popular for many reasons, including its accessibility and the conversion of sunlight into electrical energy has significant implications. This paper presents the design, performance analysis, and optimization of a hybrid microgrid for the Hamedan University of Technology, using multiple energy resources optimization software (HOMER). In the aforementioned microgrid design, photovoltaic panels, wind turbines, diesel generators, batteries, converters, and loads are integrated as a combined system. The costs associated with global deployment and the lifespan of the microgrid are taken into account in the 20-year period. The simulation results show that in the first scenario, using 50 kW of solar energy and 15 kW of wind energy. The amount of energy purchased from electricity network will be reduced by 117,021 kWh per day, which will reduce the cost of electricity. The consumption and release of carbon dioxide in the amount of 71,153 kilograms of carbon dioxide also exceeds the consumption of the contract. The electricity bill, which is accompanied by the implementation of the penalty, prevents the second statute, which was amended to include a hybrid microgrid system. The proposal will meet the university's energy needs in a sustainable manner and independent of the grid, with the aforementioned microgrid 27.63 percent renewable energy penetration rate contributes to the clean campus concept.
