摘要

本文介绍了一种采用DC-DC降压-升压变换器的高精度光伏仿真系统。模拟器的实现使用ATmega1280微控制器，允许在用户定义的天气条件下，在低成本系统中模拟光伏模块。利用MATLAB/Simulink建立了一个基于直线模型的数学模型，以再现太阳能电流-电压特性，并提出了适当的控制方案，以提高模拟器输出的性能。结果表明，在不同的天气和负载条件下，模拟器的输出特性与实际太阳能电池板的输出特性非常一致。

Design and Realization of a Low-Cost and High Accurate Photovoltaic Emulator System Using Buck-Boost Converter

This paper presents a high-accuracy photovoltaic emulator system using DC-DC Buck-Boost converter. The realization of the emulator is carried out using an ATmega1280 microcontroller, allowing the emulation of photovoltaic modules in a low cost system with weather conditions defined by the user. A mathematical model based on straight lines model is built using MATLAB / Simulink in order to reproduce the solar current-voltage characteristics and an appropriate control scheme to improve the performance of the emulator’ output. As a result, the output characteristics of the emulator are in good agreement with the ones of the actual solar panel in different weather and load conditions.
