ملخص المقالة :
بارزدایی، آخرین واکنش برای کنترل و پایداری سیستم قدرت در هنگام وقوع اغتشاش است. تعیین محل و مقدار بارزدایی از مسایلی است که همواره گریبان‌گیر بهره‌برداران سیستم قدرت بوده است. در اين مقاله روش جدیدی براي تعیین باس مناسب جهت انجام بارزدایی ولتاژی پیشنهاد می‌شود. در روش پيشنهادشده بر خلاف روش‌های پيشين از دو شاخص حساسيت ولتاژ نسبت به توان اکتيو و توان راکتيو بارها استفاده می‌شود تا باس مناسب جهت بارزدایی ولتاژي مشخص شود. در نظر گرفتن توان راکتیو بارها در فرایند تعیین باس مناسب برای بارزدایی ولتاژی باعث قطع توان راکتیو بیشتر در پله‌هاي ابتدايي بارزدايي ولتاژی شده و پروفيل ولتاژ بهبود می‌یابد. در نتیجه، توان اکتیو کمتری توسط بارزدایی ولتاژی قطع می‌شود. روش پيشنهادي به همراه روش مبتني بر حساسيت ولتاژ نسبت به توان اکتيو در شبکه تست 118باسه IEEE و شبکه 39باسه New England پياده‌سازي مي‌شوند تا درستی روش پیشنهادشده مورد بررسی قرار گیرد. نتایج حاصل نشان‌دهنده برتری روش پیشنهادی نسبت به روش حساسیت ولتاژ نسبت به توان اکتیو است.
