Abstract

Abstract. Energy is the foundation of a developing economy. In general, new energies provide a discontinuous flow of energy. For this reason, it is very difficult to match supply and demand according to production and consumption rates. Renewable energy sources, as useful as they are, require a backup energy storage system to store energy for times when the sun is not shining or the wind is not blowing. Unlike fossil or nuclear fuels, the amount and timing of renewable energy inputs are often beyond human control. Energy storage is one of the most important known human technologies for meeting needs. Pay special attention to the issue of energy storage. In this paper, to investigate the effect of renewable energy sources in evaluating the reliability of electricity distribution networks first, Quasi-Dynamic analysis was performed on the studied system. In this simulation, first, the characteristics of some elements are presented in the form of a table and then the simulation results for a group of other elements are expressed graphically. Transient stability for single-phase fault modes has been investigated for the batteries contained in DIgSILENT and electric vehicles. Also, harmonic analysis was performed on the PCC bus in the presence of three solar, wind, and electric generators. Finally, an EV collector battery model is designed. DIgSILENT Power Factory is used to perform the simulation analysis.

Keywords: Vehicle-to-grid, Integration of solar and wind system, DIgSILENT, Storage battery.

 

چکیده

انرژی زیربنای اقتصاد در حال توسعه است. به طور کلی، انرژی‌های جدید یک جریان ناپیوسته انرژی را فراهم می‌کنند. به همین دلیل تطبیق عرضه و تقاضا با توجه به میزان تولید و مصرف بسیار مشکل است. منابع انرژی تجدیدپذیر، به همان اندازه که مفید هستند، به یک سیستم ذخیره انرژی پشتیبان نیاز دارند تا انرژی را برای مواقعی که خورشید نمی‌تابد و یا باد نمی‌وزد، ذخیره کند. برخلاف سوخت‌های فسیلی یا هسته‌ای، مقدار و زمان‌بندی انرژی‌های تجدیدپذیر غالباً خارج از کنترل انسان است. ذخیره انرژی یکی از مهم‌ترین فناوری‌های شناخته شده بشر برای رفع نیازها است و باید به این موضوع توجه ویژه‌ای بشود. در این مقاله به منظور بررسی تاثیر منابع انرژی تجدیدپذیر در ارزیابی قابلیت اطمینان شبکه‌های توزیع، ابتدا تحلیل شبه دینامیکی بر روی سیستم مورد مطالعه انجام شده است. در این شبیه‌سازی ابتدا ویژگی‌های برخی از عناصر در قالب جدول ارائه شده و سپس نتایج شبیه‌سازی برای گروهی از عناصر دیگر به صورت گرافیکی بیان شده است پایداری گذرا برای خطای تک فاز در باتری‌های موجود در DIgSILENT و وسایل نقلیه الکتریکی بررسی شده است. همچنین آنالیز هارمونیک بر روی باس PCC با حضور سه ژنراتور خورشیدی، بادی و الکتریکی انجام شده است و در نهایت یک مدل باتری کلکتور EV طراحی شده است. برای انجام تحلیل شبیه‌سازی از DIgSILENT Power Factory استفاده شده است.

کلمات کلیدی: وسیله نقلیه به شبکه، ادغام سیستم خورشیدی و بادی، DIgSILENT، باتری ذخیره سازی.
