摘要

光伏(PV)组件的整体性能随辐照度、温度和阵列配置的变化而变化。因此，有必要研究这些效应与光伏阵列输出功率的关系。本文介绍了一种基于MATLAB-Simulink的光伏模块，该模块由s函数生成器和可控电流源组成。在s函数构建器中，通过一些预消化函数推导出建模方案。为了揭示非均匀辐照条件下PV组件的I-V和P-V特性，对PV组件进行了串联和并联配置。结果表明，存在多个峰，使得特征更加复杂。所提出的模型有助于验证新的全局最大功率点跟踪(MPPT)技术，并有助于设计具有最大功率的最佳光伏阵列配置。

Study of PV array configuration and its effects on performance under non uniform irradiance

Overall performance of the photovoltaic (PV) module varies with the varying irradiance, temperature and array configuration. Hence, it is essential to study the relationship between these effects and output power of PV array. This paper presents a PV module which is based on MATLAB-Simulink consisting of S-function builder and controlled current source. The modeling scheme in S-function builder is deduced by some pre-digested function. The series and parallel configuration of PV module is done to reveal the I-V and P-V characteristics of the PV under nonuniform irradiance conditions. The results show there exits multiple peaks which makes the characteristics more complicated. The proposed model assists in validating new global Maximum power point tracking (MPPT) techniques and will help to design best PV array configuration with the Maximum power.
