Power quality improvement in PV grid connected system by using active filter

Abstract

This paper present a power quality problems a raised by changes in weather conditions like solar radiations and the variation in the load connected with the system. These power quality problems like voltage fluctuation, voltage distortion, and harmonics at the L.T. line are generated by source and load also at the PCC. In this paper discuss the Power quality problem in presented 30.36kw PV plant and mitigation technique for it using active filters.
