ملخص المقالة :
سرعت افزایش سطح نفوذ منابع تولید پراکنده در شبکه قدرت و ماهیت تصادفی این منابع، نحوه بهرهبرداری و طراحی این شبکهها را دستخوش تغییر کرده که مدیریت توان راکتیو در شبکههای توزیع از این دسته هستند. استفاده از این منابع در شبکههای توزیع بدون چالش نیست و عدم مدیریت بهینه توان راکتیو ممکن است که بهرهوریهای اقتصادی برای شبکه به همراه نداشته باشد. سیستمهای ذخیرهساز انرژی، پتانسیل حل این مشکل را دارند؛ لذا در این مقاله، مدیریت توان راکتیو در یک ریزشبکه متصل به شبکه اصلی با درنظرگرفتن منابع تولید پراکنده (DG)، سیستمهای ذخیره انرژی الکتریکی (BESS) و تجهیزات جبرانکننده توان راکتیو گسسته شامل بانکهای خازنی با درنظرگرفتن عدم قطعیت در بار شبکه و تولید توان نیروگاه بادی و خورشیدی انجام شده است. نهایتاً کارایی روش بیانشده با انجام مطالعات عددی بر روی شبکههای توزیع 33 و 69شینه IEEE و در محیط نرمافزار بهینهسازی GAMS پیادهسازی گردیده است.
