Abstract

This article presents an online tool to model the characteristic I-V curve of a photovoltaic (PV) panel in real time. This tool is implemented on a friendly web (https://www.pvmodel.umh.es) and its use is completely free. The main functionality is the calculation of the five parameters of the PV single-diode model, either with real measurements of the PV module or with the data provided in the datasheet of a PV module. In the first case, the two methods that currently obtain the best results so far in two well-known cases study in the literature, the so-called Two-step linear least-square (TSLLS) method and the Reduced Form (RF) method, can be executed, in the second case, it is used a new method that allows obtaining the infinite sets of five parameters that satisfy the three remarkable points of the datasheet, that is, the short-circuit, the open-circuit and the maximum power points. Besides the PV model calculated can be also downloaded as an LTspice subcircuit so it can be used directly in electric or electronic simulations. In addition, some I-V curves data examples and PV modules datasheets data are provided so the user can test the tool directly.

PVMODEL:一个在线光伏建模工具

本文介绍了一种实时建模光伏板特性I-V曲线的在线工具。这个工具是在一个友好的网站(https://www.pvmodel.umh.es)上实现的，它的使用是完全免费的。主要功能是计算PV单二极管模型的五个参数，可以使用PV组件的实际测量值，也可以使用PV组件数据表中提供的数据。在第一种情况下，可以执行目前在文献中两个著名案例研究中获得最好结果的两种方法，即所谓的两步线性最小二乘(TSLLS)方法和简化形式(RF)方法，在第二种情况下，使用一种新的方法，可以获得满足数据表的三个显著点，即短路点，开路点和最大功率点的五个参数的无限集。此外，计算的PV模型也可以作为LTspice子电路下载，因此它可以直接用于电气或电子模拟。此外，还提供了一些I-V曲线数据示例和PV模块数据表数据，以便用户可以直接测试工具。
