چکیده

ریزشبکه‌ها مجموعه‌های ادغام‌شده از دستگاه‌های الکتریکی هستند که می‌توانند انواع تولیدکنندگان قابل‌پخش و غیرقابل‌پخش، مصرف‌کنندگان و ذخیره‌کننده‌های انرژی را شامل شوند. از طرفی دیگر مدیریت بهینه این دستگاه‌های یکپارچه با توجه به ذات تصادفی تولید تجدیدپذیر و همچنین عدم‌قطعیت در میزان بار مصرفی و قیمت‌های بازارهای الکتریکی مستلزم استفاده از روش‌های برنامه‌ریزی تصادفی است. در این مقاله یک مدل جامع برای استراتژی پیشنهاددهی ریزشبکه‌های تجدیدپذیر در بازار انرژی و رزرو روز بعد ارائه‌شده است که در آن عدم‌قطعیت در میزان تولید توان‌های بادی و خورشیدی و میزان بار مصرفی با به‌کارگیری روش برنامه‌ریزی تصادفی دومرحله‌ای وارد مسئله می‌شود. از روش نمونه‌گیری مکعب لاتین برای تولید سناریوهای توان و مصرف و از روش کاهش سناریو ترکیبی روبه‌عقب و روبه‌جلو سریع برای کاهش سناریوهای تولیدشده استفاده‌شده است. مسئله بهینه‌سازی به‌دست آمده یک مسئله عدد صحیح-مختلط غیرخطی با متغیرهای دودویی فراوان است که با استفاده از ترکیب حل‌کننده‌های Lindiglobal و AlphaECP در گمز بیشینه شده و بهینه‌های جهانی آن به‌دست می‌آیند. معیار «ارزش راه‌حل تصادفی» کارآمدی روش برنامه‌ریزی تصادفی را نشان می‌دهد.

چکیده [English]

Micro-grids are integrated electrical systems, which can include dispatchable and non-dispatchable resources, consumption and battery storages. However, optimal management of these integrated systems requires stochastic programming approaches to consider the random nature of renewable generation and consumption. In this paper, a comprehensive bidding strategy model has been provided for renewable micro-grids to participate in the day-ahead energy and reserve markets. The uncertainties in renewable generation and load consumption have been integrated to the problem by the use of stochastic programming approach. Furthermore, the Latin Hypercube Sampling and Fast Backward/forward scenario reduction approaches have been utilized to generate and reduce the scenarios. A large size mixed integer non-liner problem with a lot of binary variables is the outcome of the optimization problem, which is maximized via combination of AlphaECP and Lindoglobal solvers in GAMS to guarantee the global solutions. The “value of the stochastic solution” shows the efficiency of the stochastic programming approach.
