چکیده مقاله :
در سال¬های اخیر استفاد از منابع انرژی تجدیدپذیر به منظور تولید برق در سیستم قدرت رشد زیادی داشته¬ است. این منابع نسبت به سوخت¬های فسیلی آلودگی محیط زیست نداشته و نگرانی از پایان یافتن آن¬ها وجود ندارد. مشکل منابع انرژی تجدیدپذیر این است که توان تولیدی آن¬ها به دلیل تغییرات این منابع، متغیر می¬باشد. بر همین اساس به منظور کاهش عدم قطعیت توان تولیدی منابع انرژی تجدیدپذیر، سعی می¬گردد این منابع به صورت ترکیبی استفاده شوند. در این مقاله روشی به منظور تعیین ترکیب مناسب از منابع انرژی تجدیدپذیر جهت کاهش عدم قطعیت توان تولیدی آن¬ها معرفی می¬گردد. در این روش میانگین، انحراف معیار و همچنین هیستوگرام مربوط به توان تولیدی ساختار هیبرید به دست آمده و بر این اساس ساختاری که عدم قطعیت کمتری داشته باشد مشخص می¬گردد. روش پیشنهادی به منظور تعیین ساختار مناسب از واحدهای تجدیدپذیر در منطقه بوشهر مورد استفاده قرار گرفته است.
In recent years, the use of renewable energy sources to produce electricity in the power system has grown a lot. Compared to fossil fuels, these resources do not pollute the environment and there is no concern about their depletion. The problem of renewable energy sources is that their production power is variable due to the changes of these sources. Accordingly, in order to reduce the uncertainty of the production capacity of renewable energy sources, it is tried to use these sources in a combined manner. In this article, a method is introduced to determine the appropriate combination of renewable energy sources in order to reduce the uncertainty of their production power. In this method, the average, standard deviation, and the histogram related to the production power of the hybrid structure are obtained, and based on this, a structure with less uncertainty is determined. The proposed method has been used to determine the appropriate structure of renewable units in Bushehr region.
