ملخص المقالة :

انگیزه کاهش آلایندگی‌های زیست محیطی و حفظ محیط زیست سبب رشد سریع منابع انرژی تجدیدپذیر و مزارع بادی در سیستم‌های قدرت شده است. با این حال، چندین چالش فنی در نفوذ بالای منابع انرژی تجدیدپذیر و مزارع بادی رایج است. مهمترین چالش، دستیابی به پایداری فرکانس در سیستم‌های جدید است. زیرا این منابع جدید توان ذخیره کمتری را به نسبت ژنراتورهای سنکرون ارائه می‌دهند. علاوه بر این، بدلیل اتصال مزارع بادی از طریق مبدل‌های الکترونیک قدرت به شبکه AC، سیستم‌های قدرت جدید اینرسی کمی دارند و مزارع بادی در عملکرد عادی نمی‌توانند با سایر منابع تولید متعارف در تنظیم فرکانس مشارکت داشته باشند. اخیرا با گسترش روزافزون مزارع بادی در سیستم-های قدرت مشارکت دادن آنها در پشتیبانی و تثبیت فرکانس در شرایط بروز اختلال در تولید یا مصرف سیستم‌های قدرت بسیار مورد توجه قرار گرفته است. بنابراین در این تحقیق ابتدا نحوه شبیه‌سازی اینرسی ژنراتورهای سنکرون در توربین‌های بادی در جهت افزایش اینرسی سیستم‌های قدرت و کنترل فرکانس مورد بحث و بررسی قرار گرفته است. سپس مروری بر انواع راهبرد‌ها و آخرین پیشرفت‌های صورت گرفته در زمینه رفع چالش‌های حضور مزارع بادی در جهت پشتیبانی موقت فرکانس در سیستم‌های قدرت انجام شده است. نهایتا مطالعات انجام شده در تکنیک‌های کنترل اینرسی و فرکانس سیستم برای توربین‌های بادی سرعت متغیر مورد بررسی، دسته‌بندی و مقایسه قرار گرفته است.
