Abstract :
This paper presents the common problems encountered in a Photovoltaic (PV) connected power grid, with a special focus on the voltage profile at the point of common coupling (PCC) between a PV and a distributed generation (DG) system. This is achieved through simulations and modeling. Voltage control methodologies have been proposed to deal with the problem of increased voltage at PCC and the nearby bus bars. The harmonic impact of PV power integration at the PCC is analyzed and a three phase harmonic filer is designed to mitigate the total harmonic distortions. The investigated system performance is improved using a solar tracker control technique and using a DC-DC converter.
