Distribution Grid Three-Phase Power Flow Algorithm Based On Flow Model

Distribution grid analysis is based on distribution grid power flow calculation. New power flow algorithm for distribution network is developed. Three-phase flow model is presented. The presented model is a development of single-line flow model. Three-phase flow model give the opportunity use advantages of flow model and take into account unbalanced condition of distribution grids. In addition, in three-phase power flow there is a convergence problem in system with wye delta transformer. Presented three-phase flow model solve this problem. Comparative numerical analysis with another three-phase power flow methods performed. Experiments show that presented flow model has better convergence characteristics.
