This paper presents improvement in power quality in a grid connected with nonconventional energy source and nonlinear load. Three phase shunt active filter is proposed forimprovement in power quality. Harmonic are declining power quality which is to be filtered. Presentday energy demand is very high and conventional energy sources are costly and pollute environment.Renewable source of energy are emerging with new technology. This paper presents the model of PVpanels connected with voltage source inverter, which are stepped up by transformer and is fed to thegrid.Here Shunt active filter is implemented with voltage source inverter and dc link capacitor.Synchronous reference frame method is implemented for current control in shunt active filter. Filtercan efficiently respond to sudden change in load is depicted in this paper. THD is not much affectedwith sudden change in load. Active power transfers from PV connected inverter to the grid throughtransformer.
