基于改变比例因子的变步长最大功率跟踪算法
Variable step size MPPT method based on variable scaling factor
摘要
Abstract
Through the analysis of the characteristics of photovoltaic cell,because the traditional variable step size conductance increment method is unable to satisfy both tracking speed and reducing volatility,a variable step size MPPT method based on variable scaling factor was proposed;a different step length scaling factor was chosen by judging the state of the working point in real time,fixing the contradiction between the dynamic response and the steady-state fluctuation.The simulation results show that the improved variable step incremental conductance method make tracking process more efficient and tracking result more accurate.This method also reduces the oscillation of the maximum power point (MPP).The improved method shows good dynamic response and steady-state performance.关键词
