ملخص المقالة :
اخيراً توليد برق از باد به‌عنوان يک منبع انرژي تجديد‌پذير در بسياري از کشورها مورد توجه قرار گرفته است. با روند رو به افزايش نفوذ مزرعه‌های بادي در سيستم‌هاي قدرت، اصلاح روش‌هاي موجود ارزيابي و مديريت اين سيستم‌ها امري اجتناب‌‌ناپذير است. بررسي قابليت تبادل شبکه انتقال يکي از مطالعات مهم در سيستم‌هاي قدرت تجديدساختار يافته است که به‌منظور ارزيابي حد تبادل توان ميان نواحي سيستم از طريق شبکه و مديريت تبادلات آتي انجام مي‌شود. در اين مقاله چگونگی ارزيابي احتمالاتي قابليت تبادل در سيستم‌هاي قدرت چندناحيه‌اي برخوردار از مزرعه‌هاي بادي مطرح مي‌شود. ابتدا روش کلی ارزیابی با استفاده از شبيه‌سازي مونت‌کارلو، با لحاظ تغییرات بار شبکه و توان خروجي مزرعه بادي مطرح می‌گردد. در هر تکرار شبيه‌سازي، قابلیت تبادل با استفاده از برنامه‌ريزي رياضي مبتني بر پخش بار بهينه محاسبه مي‌شود. سپس تغییرات احتمالاتی قابلیت تبادل برای یک سطح بار ثابت مورد بررسی قرار گرفته و استفاده از تحليل ريسک به‌عنوان ابزار تصميم‌گيري و سنجش پيشنهاد می‌شود. در ادامه تغییرات توأم باد و بار برای ارزیابی قابلیت تبادل لحاظ‌شده و کاربرد روش دسته‌بندي اطلاعات در کاهش واریانس شبيه‌سازي مونت‌کارلو مطرح مي‌شود. کارايي روش‌هاي پيشنهادي با استفاده از شبکه آزمون 24 باسه IEEE - RTS مورد بحث قرار مي‌گيرد.
