چکیده

با تبدیل شبکه‌های توزیع سنتی به شبکه‌های توزیع فعال احتمال وقوع تراکم نسبت به گذشته افزایش‌یافته است، از طرفی وجود عدم‌قطعیت عواملی مانند خودروهای الکتریکی درحال شارژ یا تولید انرژی پنل‌‌های خورشیدی، سبب می‌شوند قابلیت پیش‌بینی‌پذیری تراکم در شبکه کاهش‌یابد و وقوع تراکم به‌صورت احتمالی بیان شود. این موارد باعث افزایش نگرانی اپراتورهای سیستم‌های توزیع برای وقوع تراکم در شبکه‌های توزیع از یک‌سو و از یک‌سوی دیگر، مدیریت مقدار تراکم خطوط با حداقل هزینه‌ها شده‌است. لذا ارائه راهکارهای عملیاتی جهت مدیریت‌تراکم در کمترین زمان و هزینه یک اولویت برای اپراتورها است. یکی از این گزینه‌ها، عملیات بارزدایی است. در این مقاله، راهکاری برای مدیریت‌تراکم مبتنی بر عملیات بارزدایی ضمن در نظر گرفتن عدم قطعیت‌های خودروهای الکتریکی و پنل‌های خورشیدی ارائه‌شده‌است. در گام نخست، جهت تخمین مقدار عمق و بازه‌زمانی تراکم، مدل‌سازی تراکم از طریق پخش‌بار احتمالاتی تقریبی بر اساس روش 2M+1 صورت می‌گیرد. ارزیابی روش پیشنهادی در شبکه توزیع خانگی Modified IEEE 33- bus، ضمن اثبات کارایی نشان می‌دهد با استفاده از این روش، اپراتور عملیات بارزدایی را با کمینه‌سازی هزینه‌های قطع‌بار از طریق مدل‌سازی پخش‌بار بهینه جریان‌متناوب چند بازه‌ای بهبودیافته اجرا می‌نماید و میزان تراکم‌های احتمالی بسته به میزان ریسک‌پذیری اپراتور کاهش می‌یابد.

چکیده [English]

With the transformation of traditional distribution networks (DNs) into active DNs, the possibility of congestion has increased. Also, the presence of uncertainty in factors such as electric car charging or solar panels, causes the predictability of congestion in the DN to decrease and the occurrence of congestion can be expressed as a probability. These cases have increased the concern of distribution system operators for the occurrence of congestion in DNs and also, for managing the amount of congestion with minimum costs. Therefore, providing solutions for congestion management in the shortest time and cost is a priority for operators. In this article, a solution for congestion management based on load shedding while considering the uncertainties of electric vehicles and solar panels is presented. At first, to estimate the amount of depth and time of congestion, modeling of congestion is done through probabilistic power flow. The evaluation of the proposed method in the Modified IEEE 33-bus home DN, while proving its effectiveness, shows that by using that, the operator performs the load shedding by minimizing their costs through improved multi-interval optimal power flow, and the amount of possible congestion is reduced depending on the level of risk-taking of the operator.
