Impact of three-phase inverter-based generating units with asymmetrical power redistribution on the low-voltage network operation

The aim of this paper is to describe the current state of the art in the field of energy management for three-phase asymmetrical inverters. Due to the lack of standardization in this area, the power redistribution algorithm into the three-phases is done by manufacturers with respect to covering loads while minimizing the stress on the power electronics of the inverter; but without considering the backward effects on the low-voltage network. Techniques that simultaneously minimize the effects on the low-voltage network while allowing active compensation for amplitude voltage asymmetry are presented in this paper.
