基于变尺度混沌优化搜索的局部阴影条件下光伏阵列MPPT研究
MPPT of PV array under partial shading conditions based on mutative scale chaos optimizing search
摘要
Abstract
To improve the speed and efficiency of chaos search for MPPT of PV array under the condition of partial shading,a novel mutative scale chaos optimization method was proposed.In the process of chaos search,firstly,the Logistic mapping was used as the carrier process to produce the chaos variables,and mapped them to the output voltage space of PV array;then,the mutative scale method was used to decrease the search space of optimized variables,and found the maximum power point eventually.The results show that the proposed method can track the change quickly and accurately,and it provides a new efficient way to track the maximum power point of PV array under partial shading conditions.关键词
