Abstract – Renewable Energy supply (RES) integrated at distribution level is understood as Distributed Generation (DG). This paper presents a bearing strategy for achieving most edges from these grid-interfacing inverters once put in in 3-phase 4-wire distribution systems. The electrical converter is controlled to perform as a multi-function device by incorporating active power filter practicality. The convertor} will therefore be used as: 1) power converter to inject power generated from RES to the grid, and 2) shunt APF and L,C Filter to compensate current unbalance, load current harmonics, load reactive power demand and cargo neutral current. Dynamic Voltage renovator to compensating the Voltage sags and swells. All of those functions is also accomplished either severally or at the same time. With such a bearing, the mixture of grid-interfacing electrical converter and therefore the 3-phase 4-wire linear/non-linear unbalanced load at purpose of common coupling seems as balanced linear load to the grid.
