Abstract

In this paper, the influence of serial resistance Rs and shunt resistance Rsh for PV cells are studied. The series resistance Rs has a great influence on the output characteristics of the PV cells. Therefore, it is particularly important to solve the value of Rs for the model of solar cells. Rsh is very large, in the process of PV modular modeling, the value of Rsh can be neglected. Maximum power point tracking(MPPT) algorithms play an important role in the optimization of the power and the efficiency of a photovoltaic(PV) generation system. According to the contradiction of the classical Perturb and Observe(P&O) method between the corresponding speed and the tracking accuracy on steady-state, an improved MPPT method has been put forwarded in this paper. According to establishing control model and using MATLAB/Simulink to simulate the main circuit and control system, we made the comparison among P&O method and improved P&O method. In particular, this study compares the behaviors of each technique in presence of solar irradiation variations.We have also compared the output power of the system with two MPPT method.
