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