Abstract

Abstract : In this work, a novel control of single‐phase solar photovoltaic (PV) fed unified active power filter (PV‐UAPF) is proposed for use in low‐voltage distribution system. The shunt voltage source converter (VSC) of PV‐UAPF mitigates current power quality issues such as current harmonics, reactive current etc. while the series VSC of PV‐UAPF protects the sensitive load against point of common coupling (PCC) voltage disturbances. The shunt VSC control is based on extraction of fundamental load active current using recursive least squares with a variable forgetting factor. The proposed method improves the dynamic response of the system without sacrificing the steady‐state performance. The series VSC is controlled using a proportional‐resonant controller and it injects voltage in/out phase with PCC voltage during voltage sags/swells, respectively. The PV array which is integrated at the DC link of the PV‐UAPF through a reverse blocking diode, provides the load power demand and also supplies remaining power into PCC. The system performance is evaluated using Matlab‐Simulink software and is then experimentally verified on a prototype developed in the laboratory under steady‐state and dynamic conditions such as irradiation variation, PCC voltage fluctuations and load disturbances to validate the performance of the system.
