An Advanced GIS-based Tool for the Analysis of Future Distribution Networks

The growing integration of distributed energy resources (DER) into distribution networks is increasing the complexity of planning and operational tasks carried out by distribution network operators (DNOs). To achieve this in a timely manner, they need new advanced analysis tools to adequately quantify the impacts and the benefits from potential solutions to be seen in future distribution networks. In this context, this paper presents in detail the architecture and implementation of an advanced geographic information system (GIS)-based planning tool, named OpenGIS, to assess the impacts of DER on distribution networks, and to investigate potential solutions for thermal and/or voltage problems. OpenGIS provides a user-friendly graphical user interface, flexible analysis with detailed results in a GIS environment, and is built through the integration of free-license software packages. A real UK low voltage network with residential photovoltaic (PV) systems is used to demonstrate the different features of the tool.
