一种光伏全局最大功率点跟踪控制方法研究OA
Research on Photovoltaic Global MPPT Control Method
当太阳能光伏阵列表面有局部阴影时,其功率-电压特性曲线具有多个峰值,传统的最大功率点跟踪算法无法准确搜索到光伏阵列的全局最大功率点.新兴的人工智能算法为解决该问题提供了新思路,但其实施过程复杂,算法应用有一定的局限性.为此提出一种基于负载特性的光伏全局最大功率点跟踪算法,首先,基于负载特性对光伏阵列最大功率点展开粗略搜索;其次,基于扰动观察法实施精确定位;最后,通过仿真分析验证了该算法的可行性与有效性.
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.
