Power flow solution for multiphase unbalanced distribution networks with high penetration of photovoltaics

Power flow analysis on a Photovoltaic System (PV)-dominated distribution network is rather different than a conventional distribution system. This paper proposes a new three-phase power flow solution for such networks that considers the multiphase unbalanced nature of distribution systems together with different system topologies. Power flow contributions of PVs and different types of loads are also considered. The performance of the proposed method has been assessed by simulations on a sample distribution network.
