OpenDSS-Based Distribution Network Analyzer in Open Source GIS Environment

Abstract

The adoption of low carbon technologies (e.g., photovoltaic systems) is expected to increase in the near future given their contribution to reduce greenhouse gas emissions. However, high penetrations of these new technologies are likely to result in technical problems on the distribution networks. To truly understand these impacts, nonetheless, utilities need to have detailed models of their networks and advanced simulation tools, so studies can then be performed. This paper presents an OpenDSS-based distribution network analyzer in an open source GIS environment that enables engineers to easily carry out complex network analyzes ranging from snapshot to harmonic power flows. Critical to facilitate its use, the simulation tool needs limited input information to undertake these detailed studies. Illustrations on a real distribution network with more than 10,000 customers demonstrate the efficiency of the analyzer to perform studies, display and store the corresponding results.
