Intelligent control technique for MPPT of PV system

Abstract

In recent years, the solar energy plays an important role in the area of producing electricity, the produced energy should be effectively used. So it is essential to operate Photovoltaic (PV) system at the optimal point to obtain the possible maximum efficiency. But non linear characteristics of P-V curve exhibit several local peaks and only one global peak. MPPT techniques fail to track maximum power of optimal point under partial shading technique. This paper gives new intelligent control technique in order to track the global maxima of PV power effectively and also gives the simulation result.
