doi:10.11985/2017.05.009

Abstract

Abstract:

According to the problem of energy shortage and environmental pollution in large environment, a new modeling method of the new energy photovoltaic cell is proposed. Analyzing the common MPPT algorithm of photovoltaic cells, the disturbance observation method is improved on the basis of the analysis, which overcomes the shortcomings of traditional disturbance observation at a distance of maximum power point . Using Matlab / Simulink simulation platform to build a mathematical model of photovoltaic cells, and the control circuit is built according to the improved MPPT algorithm. The results show that the mathematical model can simulate the actual working characteristics of photovoltaic cells well, and the improved algorithm can make up for the deficiency of the traditional algorithm, which can realize the maximum power point tracking.

Key words: Photovoltaic cell, disturbance observation method, variable step, Matlab/Simulink, maximum power point tracking
