Design of stand alone PV system for DC micro gridS

Abstract

This paper provides modeling of photovoltaic (PV) panel, designing of maximum power point tracking (MPPT) control algorithm for a standalone PV based distributed generation (DG) system. A detailed mathematical model of PV panel is provided. One of the most classical MPPT (Perturb and Observe MPPT) is used to track the maximum power point of the system. SunPower PV array are considered and simulation results showcase the module characteristics and array characteristics. A detailed design technique is provided for MPPT technique and simulation are carried out with varying solar irradiance.
