In this work, a novel technique based on second order sequence filter and proportional resonantcontroller is proposed for control of universal active power filter integrated with PV array system(UAPF-PV). Using a second order sequence filter and sampling it at zero crossing of instant ofthe load voltage, the active component of distorted load current is estimated which is further usedto generate reference signal for shunt active filter. The proposed method has good accuracy inextracting fundamental active component of distorted and unbalanced load currents with reducedmathematical computations. Along with power quality improvement, the system also generatesclean energy through the PV array system integrated to its DC-bus. The UAPF-PV systemintegrates benefits of power quality improvement and distributed generation. The systemperformance is experimentally evaluated on an experimental prototype in the laboratory under avariety of disturbance conditions such as PCC voltage fall/rise, load unbalancing and variation insolar irradiation
