Analysis of Tracking MPPT in Photovoltaic Arrays under Shadow Conditions Based on FP&O-IWSO Method

阐述一种模糊逻辑扰动观察法复合改进战争策略算法,追踪阴影条件下最大功率点。该方法利用模糊逻辑观察法预先追踪到系统运行的最大功率点附近,然后采用改进战争策略算法准确寻找系统当前最大功率点。改进战争策略算法在阴影条件下追踪功率时不易陷入局部最优并及时响应系统的I/V变化。通过搭建多个仿真模型,对比证明该算法在阴影条件下追踪最大功率点的有效性。

This paper expounds a fuzzy logic disturbance observation method combined with an improved war strategy algorithm for tracking the maximum power point under shadow conditions.This method uses the fuzzy logic observation method to pre-track the vicinity of the maximum power point of the system operation,and then uses the improved war strategy algorithm to accurately find the current maximum power point of the system.The improved war strategy algorithm is not easily trapped in local optima when tracking power under shadow conditions and responds timely to the I/V changes of the system.Multiple simulation models have been built and compared to demonstrate the effectiveness of this algorithm for tracking the maximum power point under shadow conditions.
