Abstract

This paper presents the analysis of two different strategies for current injection of grid connected Photovoltaic (PV) systems. One of them is based on keeping the same phase of the grid and modifying the inverter voltage. While the other is based on a phase shifting strategy that allows for the possibility of controlling the active and reactive power injected to the grid. Harmonic and power profiles generated by both schemes are analyzed and discussed based on simulation results.
