Abstract
Renewable energy resources (RES) are connected in distribution systems utilizing power electronic converters.In this paper the maximum benefits can be achieved from these grid-interfacing inverters when installed in 3-phase 4-wire distribution systems. The inverter is controlled to perform the operation with the active power filter functionality. In this paper the boosting converter is used to inject power generated from RES to the grid, and the shunt APF is utilized to compensate current unbalance, voltage harmonics and load reactive power demand. All of these functions may be accomplished either individually or simultaneously. The combination of gridinterfacing inverter and the 3-phase 4-wire linear/non-linear unbalanced load at the point of common coupling appears as balanced linear load to the grid. This concept is demonstrated with extensive MATLAB/Simulink simulation studies.
