摘要
提出一种基于跳跃策略的跟踪算法,利用改进后的负载线函数,使工作点跳出局部最优区间,结合传统的电导增量法,能够迅速定位出各个局部区间的最大功率点,从而实现全局最大功率点的跟踪。在Matlab/Simulink中建立符合光伏组件特性的模型,通过模拟光伏阵列从光照强度均匀到局部遮挡的过程检验算法的有效性。结果表明,在光照条件变化过程中能准确定位出全局最大功率点。
A novel tracking algorithm based on the jumping strategy was proposed. The improved load line function was used to make the working point jump out of the local optimal range, and then the maximum power point in every local area was found based on the traditional conductance increment method so that the global maximum power point tracking was realized. The model simulating the characteristics of PV module was designed in Matlab/Simulink. The effectiveness of the method was checked by simulating the process of PV array from the uniform solar irradiance to partial shading condition. The results show that the method can accurately locate the global maximum power point during the radiation conditions change.
