Comparative study of new MPPT control approaches for a photovoltaic system

Abstract

The output characteristics of the photovoltaic (PV) installation normally depend on solar radiation and ambient temperature, the charge impedance, its maximum power point (MPP) is not steady. In every state of the PV module has a point where it can create its MPP. Thus, MPPT (maximum point power monitoring) process can be employed to keep the photovoltaic panel running on its MPP. In this article, the objective was to determine how the different maximum point power monitoring (MPPT) techniques applied to PV systems work. Therefore, two MPPT algorithms are offered and compared under several situation of temperature and radiation conditions: MRAC methods and sliding mode controller combined with the Incremental Conductivity (IC) algorithm. They are often employed due to their low price and simple use. They have been tested on their performance employing the PSIM software with different situations of temperature and solar radiation.
