ملخص المقالة :
در اين مطالعه، يك روش كنترلي سيستم واسط تزريق توان منابع انرژي‌هاي تجديدپذير به شبكه بر مبناي الگوريتم كمترين مربعات بازگشتي- چندخروجي توسعه يافته و با در نظر گرفتن ملاحظات مديريت توان اکتیو و كاهش مؤلفه‌هاي هارمونيكي، نامتعادلي و راكتيو جریان ارائه مي‌شود. روش پیشنهادی با شبیه‌سازی در محیط نرم‌افزار MATLAB مورد ارزیابی قرار می‌گیرد. ابتدا يك سيگنال سه‌فاز هارمونيكي نامتعادل مصنوعی تولید و به چند تخمین‌گر مختلف ارسال و خروجی آنها با هم مقايسه مي‌شود. نتایج به دست آمده، بیان‌کننده کارایی مناسب ساختار پیشنهادی در استخراج مؤلفه‌های متقارن هارمونیکی اکتیو در مقایسه با سایر روش‌های متداول است. همچنین عملكرد ديناميكي آن در دنبال‌كردن تغييرات جريان بار با به کارگیری آن در سيستم کنترلی یک سیستم واسط انرژی منبع تولید پراکنده نشان مي‌دهد كه علاوه بر مدیریت توان اکتیو تزریقی به شبکه، کاهش هم‌زمان مؤلفه‌های هارمونیکی، نامتعادلی و راکتیو جریان به خوبی انجام می‌شود.
