This paper revisits the mechanism of overvoltage and voltage unbalance production in the context of the connection of small single-phase DG units to LV distribution grids. Based on quite simplified models of typical LV distribution feeders, the phenomenon is illustrated and quantified, through the introduction of a new index (distribution factor). Finally, some mitigation solutions are investigated.
