| چکیده | ||
| Due to the increasing cost and environmental impacts of fossil fuel consumption, using the renewable energies in data center has become an important and essential priority. Although using renewable energies has less environmental harmful effects, but the high investment needed for their installations as well as their fluctuating power production characteristic, restricts their usage such that most of data centers' managers prefer to use brown energy instead. In this paper, the power management and cost reduction techniques, with the aim of reducing break-even time, like using the electricity pricing models' opportunity and distributed Uninterruptable Power Supply (UPS) has been considered. In each time slot, the proposed Smart Power Manager Unit (SPMU) specifies the optimized distribution of power between available power supplies based on available solar energy, the price of electricity and the status of distributed UPS batteries; it also manages batteries charging and discharging. Results show that proposed method reduces the break-even time of investment cost on solar power installation to 0/8- 1/2 years that is 36% shorter than conventional method on average. | ||

| چکیده [English] | ||
| توجه به مسئلۀ رشد هزینه و پیامدهای منفی مصرف سوخت‌های فسیلی، استفاده از منابع تجدیدپذیر انرژی را به اولویتی اساسی در مراکز داده تبدیل کرده است. اگرچه استفاده از این منابع موجب کاهش آثار مخرب زیست‌‌محیطی مصرف سوخت‌های فسیلی میشود، هزینۀ زیاد راه‌اندازی نیروگاه و طبیعت نوسانی این منابع، استفاده از آن را محدود می‌کند؛ بهگونهای که بسیاری از گردانندگان مراکز داده ترجیح می‌دهند از منابع برق شهری استفاده کنند. در این مقاله روش‌های مدیریت توان مصرفی و کاهش هزینه با هدف کاهش زمان بازگشت سرمایه، مانند بهرهمندی از فرصت‌های برآمده از الگوی محاسبۀ هزینۀ انرژی و مدل توزیع‌شدۀ برق اضطراری (UPS)، بررسی شده است. واحد مدیریت هوشمند توان مصرفی (SPMU) پیشنهادشده، در هر فاصلۀ زمانی با توجه به میزان انرژی خورشیدی در دسترس، قیمت برق شهری و وضعیت باتری‌های توزیع‌شدۀ UPS، توزیع بهینه‌ای از توان ذخیرهشدۀ هر منبع ارائه می‌دهد و مدیریت شارژ و تخلیۀ باتری‌ها را بر‌عهده می‌گیرد. بر اساس نتایج، این روش زمان بازگشت سرمایه را بین 2/1 - 8/0 سال کاهش می‌دهد که بهطور متوسط 36 درصد کمتر از روش مرسوم است. | ||
