摘要
基于光伏模块直流物理模型,在PSCAD仿真环境下,开发了光伏阵列仿真模型。此外,考虑到太阳能的波动性和随机性对光伏阵列的影响,开发了最大功率点跟踪(Maximum Power Point Tracking,MPPT)控制器仿真模型,保证光伏阵列在任何当前日照下不断获得最大功率输出。仿真结果表明,搭建的仿真模型能够准确的反映实际物理装置的特性与功能,可以用于光伏发电并网及储能方面的仿真研究。
A simulation model for photovoltaic array is developed based on the DC physical model of photovoitaic module under PSCAD environment. In addition, considering the solar fluctuation and randomness, a simulation model of MPPT controller is also developed to guarantee the maximum power output ofphotovoitaic array under any current sunlight. The simulation results show that the simulation models can reflect characteristics and functions of the actual physical device accurately and can be used to the simulation research on paralleling in the grid and energy storage of photovoltaic power generation.
