Open Electrical Grid Model for Regional Transmission Networks

Abstract:
This paper aims at addressing the challenges associated with open electrical grid models to advance load flow simulations required for the transition toward a sustainable energy system. This paper presents a Python-based open electrical grid model generator by using OpenStreetMap data as the input to increase the availability of open-source models for regional transmission networks. The method is based on the existing open electrical grid tool osmTGmod and consists of two main steps presented in detail. First of all, a new state-of-the-art OpenStreetMap filter is researched and implemented. It converts Open Street Map data to CSV data categorized by the corresponding object classes. Following this, missing data is populated by a Python Script depending on different heuristics. The software and packages are presented and one example of a regional transmission network is described to provide insight into the method.
