摘要
基于现有五参数模型构建了阴影条件下的光伏阵列多峰输出特性模型,该模型能够仿真阴影条件下光伏阵列的I-U性能曲线。在此多峰模型基础上,搭建了MPPT控制模型,利用优化后的PSO算法实现多峰情况下的最大功率点追踪,并与原始PSO算法进行对比,仿真结果表明该算法能够快速且准确的追踪到多峰下的最大值。
Based on the existing five-parameter model,a photovoltaic array multi-peak output characteristic model under shadow conditions was constructed,which can simulate the I-U performance curve of photovoltaic arrays under shadow conditions.On the basis of this multi-peak model,an MPPT control model was built,the optimized PSO algorithm was used to achieve maximum power point tracking under multi-peak conditions,and compares with the original PSO algorithm.The simulation results show that the algorithm can be fast and accurate for tracking the maximum value under multiple peaks.
