This paper presents development of analysis function for low voltage (LV) distribution system with distribution generators. The conventional interconnection evaluation tool had three phases unbalanced load flow calculation which made primary distribution system applicable to analysis. On the other hand, in LV distribution system, the authors are anxious about generating of the voltage rise by the photovoltaic power generation. In this paper, pole transformer model, LV distribution line model, and photovoltaic power generation model have been developed as models for LV distribution systems to analyze LV system integrated with primary distribution system.
