基于动态阻抗匹配算法的光伏组件MPPT研究
Research on MPPT of Solar Modules Based on Dynamic Equivalent Impedance Matching
摘要
Abstract
Maximum power point tracking(MPPT)is a widely used technology to improve the output power of the photovoltaic modules,based on the analysis of the existing MPPT technologies,an equivalent impedance matching (EIM)algorithm was proposed. Such algorithm found out the MPP as the solution of the equation that effective load impedance matches the internal impedance of the solar module based on the dichotomy. The unknown of the equation , the duty ratio,could be obtained through the iterative method. Compared with the state-of-the-art MPPT technologies, the EIM algorithm has the advantages of higher speed and accuracy with a simpler circuit design ,which are proved through the Matlab/Simulink simulation.关键词
