Photovoltaic (PV) power generation system is a promising source of energy with great interest in clean and renewable energy sources. And many PV systems are interconnected to the distribution system. The growing number of power electronics-based equipment has posed a problem on the quality of electric power supply. Both high power industrial loads and domestic loads cause harmonics in the utility. Power quality problems may arise in the system or may be caused by the consumer itself. Active filters (AF) have been rapidly expanding with the advancement of power electronics technology. The purpose of the active filters installed by individual consumer is to compensate current harmonics and/or current imbalance of their own harmonic-producing loads. But it requires additional costs. A Grid-connected inverter used in the PV system outputs a sinusoidal current to inject an active power to the utility. So, the PV system combined with the function of the active filter system can be useful for the application in the power distribution system. In this paper, PV-AF system using DSP (Digital Signal Processing) controller confirmed that it is possible to combine the AF theory to the three phase PV system connected to the utility.
