ملخص المقالة :
هدف از بازیابی شبکه‌های توزیع، انرژی‌رسانی مجدد به بارهای بی‌برق شده شبکه پس از رخداد خطا است که با تغییر در وضعیت کلیدهای شبکه و در نظر گرفتن قیود شبکه انجام می‌گیرد. در این مقاله، یک روش بازیابی چندمرحله‌ای با کمک روش درخت تصمیم‌گیری اصلاح‌شده جهت بازیابی شبکه‌های توزیع با هدف بازیابی حداکثر بار بی‌برق شبکه با کمترین تعداد کلیدزنی ارائه شده است. روش بازیابی چندمرحله‌ای پیشنهادشده در سه مرحله 1) بازیابی اولیه شبکه با بستن کلیدهای در حالت عادی باز شبکه، 2) بازآرایی و 3) بهینه‌سازی عملیات قطع بار انجام می‌گیرد. به منظور کاهش فضای جستجو در روند بازیابی، کلیدهای شبکه در گروه‌های مختلفی دسته‌بندی شده‌اند که از حرکت به سمت فضاهای جواب نامناسب جلوگیری می‌کند. روش پیشنهادی بر روی شبکه‌های 69باسه و 119باسه استاندارد IEEE اجرا شده است. نتایج به دست آمده بیانگر کارایی و دقت بالای روش پیشنهادی در بازیابی شبکه‌های توزیع می‌باشد.
