基于模糊控制的光伏发电MPPT控制方法
MPPT Control Method for Photovoltaic Power Generation Based on Fuzzy Control
摘要
Abstract
In order to maximize the generating efficiency of photovoltaic cells,aiming at the disadvantage of fixed step conductance increment MPPT control method,an improved MPPT algorithm with variable step conductance increment method based on fuzzy control was presented.The characteristics of photovoltaic cells were analyzed and the equivalent model was established,a photovoltaic power generation system based on Boost circuit was built,the fuzzy control rules was designed according to the input and output of the system,the appropriate membership functions were selected,and the optimal control of maximum power tracking was achieved. Through simulation and analysis,it is proved that the method is better than the traditional fixed step conductance increment method.It improves the control precision and reduces the fluctuation of output power of photovoltaic cell.关键词
