Abstract
The increasing penetration of renewable energy sources into the ac grid has brought several challenges for the power utilities, especially in the fields of power quality, stability, reliability, protection and control. In this paper, we present the design and implementation of a power flow control scheme for a photovoltaic to low voltage ac grid interface. The control algorithm is based on instantaneous tracking of the power reference signal by current regulation of the grid connected inverter. The proposed control and graphical user interface are implemented using LabVIEW. The ability of the developed system to control both the real and reactive powers injected into the grid is validated using both computer simulations and experimental tests.
