A Python-based Open-source Distribution Network Analysis ToolBox for Automated Modeling, Analysis and Visualization

With the increased penetration of distributed energy resources, it is crucial for distribution network operators to perform analysis to ensure grid stability. Technological advances in the recent years, have made it possible for the development of such tools, some of which are licensed, while others are opensourced. PSS Sincal, CYME to name a few, are commercial softwares which require license, limiting their adoption. Whereas, tools like GridLab-D and OpenDSS are open-sourced tools used to model, simulate and perform analysis of a distribution network. This paper, presents a python-based open-source DNTool, which provides automated modeling as well as visualization of the results. The developed tool uses OpenDSS, through Python interface, to model, solve and analyze the distribution network, whereas the visualization is done on PyQt5. Modeling of the network is performed in OpenDSS, through the data of the components in the distribution network provided in the form of a CSV File. The tool uses Snapshot Analysis Method to solve and perform analysis on the distribution network. The results are then visualized using PyQt5. The features of DN-Tool are exhibited for IEEE-13 bus distribution system.
