摘要
本文将改进的灰狼算法用于光伏发电系统的最大功率跟踪。对原有算法的收敛性进行优化,在引入动态加权的基础上,利用改进灰狼算法对局部阴影下的最大功率点进行跟踪。并建立局部遮蔽模拟模型进行模拟实验,在MATLAB/Simulink中构建了最大功率跟踪模型,设置太阳能板与改进灰狼算法进行对比,得到功率-时间曲线,通过MATLAB/Simulink中最大功率跟踪模型,与改进灰狼算法进行对比,得出传统跟踪方法不能追踪阴影时最大功率的结论。
In this paper, the improved gray Wolf algorithm is applied to the maximum power tracking of photovoltaic power generation system. The convergence of the original algorithm is optimized, and the improved Grey Wolf algorithm is used to track the maximum power point under the local shadow based on the introduction of dynamic weighting. The maximum power correlation tracking model is established by using MATLAB/Simulink, and the solar cell is compared with the optimized Grey Wolf algorithm, thus the maximum power change curve with time is obtained, and the maximum power is compared with the MATLAB/Simulink. The results show that, The conventional tracking method cannot track the maximum power in the shadow.
