Power flow calculation of distribution network based on the VDNAP

This article elaborates the establishment mechanism and realization method of distribution network analysis platform VDNAP (Visual Distributed Network Analysis Platform) based on geographic information systems relatively deeply, and uses the practical and efficient forward and backward substitution method based on the detailed analysis of advantages and disadvantages of existing distribution power flow calculation methods to carry out power flow calculation in VDNAP taking a single line of certain urban areas for example. The results show that distribution network power flow calculation based on VDNAP grid model analysis platform analysis with the advantages of fast calculation speed, intuitive result reflections and so on, is of great significance to the study of the Distribution Management System.
