PARAMETER EXTRACTION OF SINGLE-DIODE PV-MODULE MODEL USING ELECTROMAGNETISM-LIKE ALGORITHM

Abstract

The performance of photovoltaic (PV) module mainly depends on the parameters of electrical equivalent circuit of module. The parameters are unknown and sensitive to meteorological condition of PV location. Thus, an accurate estimation method should be used to extract the parameters. In this paper, an evolutionary algorithm proposed to optimize the parameters under various operation conditions. The root mean square error between the computed current based estimated parameters and experimental PV output current is proposed as a fitness function to obtain the optimal solution. The results are verified by seven different experimental I-V sets under various meteorological conditions. Furthermore, the results are verified by another work, which based on analytical method that proposed in literature. The results refer to high consistency with realistic data. In addition to that, the proposed method offers an average root mean square error and average absolute error under seven operation conditions were 0.07248 and 0.05316, respectively. ‫ا‬ ‫شبه‬ ‫نظرية‬ ‫بأستخذام‬ ‫كهروضىئي‬ ‫للىح‬ ‫الذايىد‬ ‫احادي‬ ‫لمىديل‬ ‫معامالت‬ ‫ستخراج‬ ‫الكهرومغناطيسية‬ :‫الخالصة‬ ‫قيى‬ ً‫عه‬ ‫االسبط‬ ‫ثبنذسرخ‬ ‫يعتًذ‬ ‫انشًسيخ‬ ‫االنىاس‬ ‫اداء‬ ٌ‫ا‬ ‫ا‬ ٌ‫تكى‬ ‫انقيى‬ ِ‫وهز‬ .‫نهب‬ ‫انًكبفئخ‬ ‫انكهشثبئيخ‬ ‫نذائشح‬ ‫تتبحش‬ ‫وهي‬ ‫يعشفخ‬ ‫غيش‬ ‫هز‬ ‫ايزبد‬ ‫في‬ ‫يستخذو‬ ٌ‫ا‬ ‫ويزت‬ ‫رذا‬ ‫يهى‬ ‫انقيى‬ ِ‫هز‬ ٍ‫تخًي‬ ‫في‬ ‫دقخ‬ ‫االكخش‬ ‫انطشيقخ‬ ‫اختيبس‬ ‫ونهزا‬ .‫انشًسيخ‬ ‫االنىاس‬ ‫نىرىد‬ ‫انزغشافي‬ ‫ثبنًىقع‬ ِ ‫استخذاو‬ ‫تى‬ ‫انجحج‬ ‫هزا‬ ‫في‬ .‫انقيى‬ ‫انت‬ ‫انخىاسصييخ‬ ‫طشيقخ‬ ‫ا‬ ‫في‬ ‫طىسيخ‬ ‫ظشوف‬ ًٍ‫ض‬ ‫قيى‬ ‫افضم‬ ‫يزبد‬ ‫انتشثيعي‬ ‫انززس‬ ‫يعذل‬ ‫استخذاو‬ ‫وتى‬ .‫يتعذدح‬ ‫نهخط‬ ‫أ‬ ‫كًعبد‬ ‫انشًسيخ‬ ‫نالنىاس‬ ‫االخشاد‬ ‫نتيبس‬ ‫انعًهيخ‬ ‫انقيى‬ ٍ‫وثي‬ ‫انًخًُخ‬ ‫انقيى‬ ‫حست‬ ‫نهتيبس‬ ‫احتسبثهب‬ ‫يتى‬ ‫انتي‬ ‫انقيى‬ ٍ‫ثي‬ ‫ن‬ ‫افضم‬ ‫العتًبد‬ ‫تقييى‬ ‫خ‬ ‫يُهب‬ ‫انتحقق‬ ‫تى‬ ‫عهيهب‬ ‫انحصىل‬ ‫تى‬ ‫انتي‬ ‫انُتبئذ‬ .‫انًخًُخ‬ ‫انقيى‬ ًٍ‫وض‬ ‫عًهيخ‬ ‫ًَبرد‬ ‫سجع‬ ‫استخذاو‬ ‫خالل‬ ٍ‫ي‬ ‫ظشوف‬ ‫انزغشافي‬ ‫نهًىقع‬ ‫يختهفخ‬. ‫اخشي‬ ‫اعًبل‬ ‫يع‬ ‫يقبسَتهب‬ ‫تى‬ ‫انُتبئذ‬ ٌ‫ا‬ ً‫ان‬ ‫ثبالضبفخ‬ ‫انًًبح‬ ‫انجحىث‬ ‫قبئًخ‬ ًٍ‫ض‬ ‫َششهب‬ ‫تى‬ .‫هخ‬ ً‫ان‬ ‫انُتبئذ‬ ‫تشيش‬ ‫كزنك‬ ‫نهُتبئذ‬ ‫عبني‬ ‫تقبسة‬ ً‫ان‬ ‫انحقيقيخ.ثبالضبفخ‬ ٌ‫ا‬ ‫انززس‬ ‫يعذل‬ ‫اعطت‬ ‫انًقتشحخ‬ ‫انطشيقخ‬ ‫نهخط‬ ‫انتشثيعي‬ ‫أ‬ ‫يعذل‬ ‫وكزنك‬ ‫انًطهق‬ ‫انًعتًذح‬ ‫ششوط‬ ‫انسجع‬ ًٍ‫ض‬ ً‫نهخط‬ ‫كبَت‬ ‫قيًهب‬ 2.270.0 ‫و‬ 2.250.0 ، ‫انتىاني‬ ً‫عه‬ .
