The issue of asymmetry in low voltage network with distributed generation

The issue of asymmetry in a low voltage network gets a new dimension with integration of distributed generation, especially within weak LV networks. The relative importance of power plant relative to the local network leads to changes in a power flow from the source to the parent network. This phenomenon raises several questions, like technical problems: issues of energy loss and a permitted increase in voltage asymmetry. The question is to what extent to tolerate the asymmetry in low voltage network, where the utilization factor is not predictable - especially with mostly mono phase network users (customers). Furthermore, if such an asymmetry becomes a problem only with the appearance of distributed source, can a symmetrical source be considered as a source of asymmetry.
