Design of PSO-fuzzy MPPT controller for photovoltaic application

Abstract

This paper focus on modeling and simulation of Photovoltaic (PV) system by using improved mathematical model. Improved mathematical model which is used to study the changes in different parameter and effects on the PV array such as operating temperature and solar irradiation level improved. In this paper PSO-Fuzzy algorithm is proposed for MPPT control. The proposed algorithm will find the suitable duty ratio in order to maximize the power output of DC-DC converter. The proposed PSO-Fuzzy MPPT controller can work in the maximum power point for the complete range of solar data (temperature and solar irradiance level).
