摘要
针对光伏组件局部遮挡时电压-功率特性曲线会出现多个极大峰值,以最大功率点跟踪(MPPT)为研究对象,提出基于改进蚁群算法的MPPT算法,通过对每条支路上的信息素进行约束来避免算法的过早停滞,并对其进行建模和仿真,得出相对于普通蚁群算法在收敛速度和精确性上有很明显的提高。通过实际工程应用发现,改进蚁群算法可以快速稳定找到最大功率工作点。
According to the partial occlusion when photovoltaic module voltage-power characteristic curve will appear multiple peaks,with the maximum power point tracking(MPPT)as research object,the MPPT algorithm based on improved ant colony algorithm is put forward ,the algorithm to avoid premature stagnation of each branch of the pheromone binding,and the modeling and simulation of its that,compared with conventional ant colony algorithm is better in convergence speed and accuracy.Through practical engineering application,it is found that the improved ant colony algorithm can quickly and stably find the maximum power work point.
