Abstract
In order to improve energy use ratio of photovoltaic (PV)generation system,a kind of maximum power point tracking (MPPT)method for segmented self-adaption of disturbance step-size is proposed by combining with characteristic of output active power-voltage curve of the PV generation system.In the process of step-size adjustment,the adjustment algo-rithm for disturbance step-size is related to infinitesimal element which means that symbol of disturbance step-size is decided by that of infinitesimal element.Meanwhile,the size of step is changed with that of infinitesimal element to realize self-a-daption adjustment and then MPPT of PV system.Simulation model is set up in MATLAB/Simulink environment to verify theoretical validity of the algorithm and adaptability to external condition changes.关键词
