PV emulation under commercially available programmable DC voltage source

Abstract

This paper aims to presents the results obtained in PV emulating with a 1,5 kW Magna-Power programmable DC voltage source, boost converter, battery bank and resistive load. For MPPT (maximum power point tracking) an improved P&O algorithm is used. Hardware implementation is done under DS 1103 controller board running Matlab and ControlDesk® software with PX4 expansion box. This paper presents a first part of a configurable microgrid which offers the possibility of implementing the behavior and the control of such systems, in grid-connected or disconnected from the national grid. Experimental results show the effectiveness of the proposed system under various conditions.
