Power quality enhancement of grid integrated solar PV system based on adaptive noise reduction control

This paper presents implementation of a two stage three phase PV-grid interfaced system with a three phase VSC which has been utilized as a multifunctional device. Adaptive noise reduction technique is used to control multifunctional VSC which transfers the active power from PV system to the grid and also works as an active power filter (APF) to improve power quality at AC mains. The control algorithm presented here has a fast and accurate dynamic response. The proposed SPV energy system has been implemented with linear and non-linear load to show harmonic elimination, load balancing and power factor correction.
