چکیده مقاله :
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.
In this paper a control technique for renewable energy resources–grid interface is proposed based on extended multi output-recursive least square (EMO-RLS) algorithm considering active power management and harmonic, unbalanced and reactive current components elimination. The proposed method is evaluated via MATLAB/SIMULINK software. Firstly, an artificial three-phase unbalanced harmonic signal is generated. It will be transmitted to different estimators for their outputs comparison. The results indicate proper performance of the suggested structure for active harmonic symmetrical components analysis in comparison with the other traditional methods. Also, its dynamic operation in tracking of load current variations is evaluated employing EMO–RLS algorithm for control system of a DG source interface. It illustrates the active power injection to the grid is managed, as well as the harmonic, unbalance and reactive current components, are decreased simultaneously.
