ملخص المقالة :
در اين مقاله يك روش جديد به منظور بازيابي حداكثر بار با تكيه بر مديريت برخي از متغيرهاي كنترلي در شرايط بروز عيب و قطعي‌هاي جزئي مانند قطع خط انتقال، خروج واحدهاي توليدي و غیره ارائه شده است. متغيرهاي كنترلي كه جهت حداكثرنمودن مقدار بار بازيابي‌شده به كار مي‌رود شامل تپ ترانسفورماتورهاي قدرت، برنامه‌ريزي مجدد واحدهاي توليد و در صورت نياز قطع بار خواهد بود. مدل‌سازي در سه مرحله انجام گرفته و اولويت بکارگيري متغيرهاي كنترلي در مراحل شبيه‌سازي متفاوت است. در مرحله اول از متغير كنترلي تپ ترانسفورماتورهاي قدرت، در مرحله دوم از مدل‌سازي هم‌زمان متغيرهاي كنترلي تپ ترانسفورماتورها و برنامه‌ريزي مجدد واحدهاي توليدي و در مرحله نهایي از بكارگيري هم‌زمان متغيرهاي تپ ترانسفورماتورهاي قدرت، برنامه‌ريزي مجدد واحدهاي توليدي و قطع بار استفاده شده است. با توجه به تعدد متغيرهاي كنترلي و غير خطي بودن فضاي پاسخ نهایي، بهينه‌سازي به كمك الگوريتم ژنتيك انجام شده و شبكه استاندارد IEEE-RTS با 24 شينه جهت بررسي قابليت‌هاي روش پيشنهادي و مطالعات عددي مورد استفاده قرار گرفته است.
