光伏电池的建模与光伏发电系统的仿真

摘要

Mathematical model of photovoltaic cell and corrected parameters are used to get performance parameters under different environment,simulation model of photovoltaic cell is established in MATLAB/Simulink environment as well,and output characteristics of photovoltaic cell under different illumination intensities and environmental temperatures are ana-lyzed and compared. This paper carries on simulating analysis on arbitrary photovoltaic power generation systems under dif-ferent illumination intensities and environmental temperatures based on incremental conductance algorithm and boost circuit. Simulation results indicate that this model is able to realize maximum power point tracking of the photovoltaic power genera-tion system and verifies it could satisfy simulation requirements of the photovoltaic power generation system.%利用光伏电池的数学模型，使用修正参数得到不同环境下的性能参数，在 MATLAB/Simulink 环境中搭建光伏电池仿真模型，并对不同光照强度和不同环境温度下的光伏电池输出特性进行分析比较。基于电导增量法与升压斩波电路，对任意给定的不同光照强度和不同环境温度下的光伏发电系统进行仿真分析。仿真结果表明，该模型可实现光伏发电系统的最大输出功率跟踪，验证了该模型可满足光伏发电系统的仿真需要。
