A new load flow and short‐circuit analysis for unbalanced modern distribution system

Abstract

This paper proposes a new load flow and short-circuit analysis method for unbalanced distribution system incorporating three-phase transformer models and inverter-based distributed generation (IBDG). Initially, a load flow method of an unbalanced distribution system is developed in this paper, which incorporates the mathematical model of three-phase transformer of any vector group and different modes of operation of IBDG.
