Renewable energy resources (RES) are being increasingly connected in distribution systems utilizing powerelectronic converters. This paper presents a control strategy for achieving maximum benefits from these grid-interfacinginverters when installed in 3-phase 4-wire distribution systems. The inverter is controlled to perform as a multi-functiondevice by incorporating active power filter functionality. The inverter can thus be utilized as: 1) power converter to injectpower generated from RES to the grid, and 2) shunt APF to compensate current unbalance, load reactive power demandand load neutral current 3) reducing the total harmonic distortion value (THD). With such a control, the combination ofgrid-interfacing inverter and the 3-phase 4-wire linear and non-linear unbalanced load at point of common coupling(PCC) appears as balanced linear load to the grid. In this paper, PV-cell is a new control concept which is demonstratedwith extensive MATLAB/Simulink software
