Numerical Simulation of New Photovoltaic System

本文采用数字仿真技术,仿真光伏系统的运行特性,建立由非线性元件(光伏方阵,蓄能部件)及负载,调节器等部件构成系统的数学模型。 根据数学模型,可以在计算机上计算出模型中任意变量的瞬时值并可任意改变参数。计算结果(瞬时值)与实测结果基本吻合,表明所建立的数学模型是合理的。

In this paper, by using numerical simnulating technique to simulate the operation character of a photovoltaic system, which is composed of nonlinear elements (photovoltaic array, battery storage), load and regulator etc., A new mathematical model of this system is established. According to this model computer simulation is used to obtain the instantaneous values of various physical arguments of this system and the calculated results are identical with the experimental results. It shows that the new model is feasible and reliable.
