基于复合算法的光伏最大功率点追踪
PV Maximum Power Point Tracking Based on Composite Algorithm
摘要
Abstract
The output power of a photovoltaic array exhibits a multi-peak state under partial shading,and traditional MPPT(Maximum Power Point Tracking)control can not solve the multi-peak problem,resulting in the system being trapped in a local optimum affecting the photovoltaic power generation efficiency.To address this issue,a hybrid algorithm is proposed for photovoltaic maximum power point tracking.This method optimizes the initial population of the sparrow algorithm and combines with reverse learning strategy to enhance the algorithm's global search ability.When the algorithm searches near the maximum power point of photovoltaic power generation,the perturbation observation method is used to quickly search the maximum power point by utilizing its fast convergence characteristics.Using Simulink simulation and hardware experimentation,the global search ability and fast convergence ability of the proposed hybrid algorithm are verified.Compared with the sparrow algorithm and perturbation observation method,the hybrid algorithm has significantly improved accuracy and speed.关键词
