文章摘要：針對(duì)現(xiàn)有光伏組件工程數(shù)學(xué)模型曲線擬合誤差較大的問題,首先基于光伏電池的物理模型推導(dǎo)開路電壓和最大功率點(diǎn)電壓與輻照度之間的函數(shù)關(guān)系,改進(jìn)不同工況下建模參數(shù)獲取的方法,提高模型在關(guān)鍵信息點(diǎn)的建模精度;然后通過分析現(xiàn)有工程數(shù)學(xué)模型的建模過程,發(fā)現(xiàn)現(xiàn)有工程模型建模參數(shù)選擇方法的不足,結(jié)合等效串聯(lián)電阻對(duì)最大功率點(diǎn)電壓的影響,提出建模參數(shù)選擇方法的改進(jìn)措施,最終建立以電壓為輸出的改進(jìn)光伏組件工程數(shù)學(xué)模型。試驗(yàn)與仿真分析表明,改進(jìn)的工程數(shù)學(xué)模型極大地提高了工程數(shù)學(xué)模型的曲線擬合精度,對(duì)不同類型組件均具有較高的建模精度。

Abstr：Aiming at the larger curve fitting error of traditional mathematic engineering model of photovoltaic module,the functional relationship between the open-circuit voltage and the irradiance as well as that between the maximum power point voltage and the irradiance are derived based on the physical model of photovoltaic cell to improve the method of modelling parameter acquisition under different operational conditions and the modelling accuracy at key information points. The establishment process of traditional mathematic engineering model is analyzed and its deficiency in the parameter selection is detected. A countermeasure is proposed according to the impact of equivalent series resistance on the maximum power point voltage and an improved mathematic engineering model of photovoltaic module is established,which takes the voltage as its output. Experiment and simulation show that,the proposed modelling method improves the curve fitting precision greatly and has higher modelling accuracy for different types of photovoltaic module.
