一种光伏全局最大功率点跟踪控制方法研究
Research on Photovoltaic Global MPPT Control Method
摘要
Abstract
When there are local shadows on the surface of the solar energy photovoltaic cell array,its power-voltage characteristic curve has multiple peaks,and the traditional maximum power point tracking(MPPT)control algorithm cannot precisely search for the global maximum power point of the photovoltaic cell array.Emerging artificial intelligence algorithms can provide new ideas for solving this problem,but their implementation process is complex and the specific application of the algorithms have certain limitations.In view of the above problems,it proposes a photovoltaic global MPPT approach based on load characteristic perturbation.Firstly,the maximum power point of the solar photovoltaic cell array is roughly located with the help of the load characteristic line.Secondly,it implements precise search based on the perturbation observation method.Finally,the simulation analysis results testify the feasibility and effectiveness of the approach.关键词
