GIS visualization of COVID-19 impact on PQ indicators in distribution networks: A case study of Croatia

A large part of 2020 and 2021 was marked by the COVID-19 pandemic. A global pandemic has caused changes in people’s behavior and has created challenges for multiple industries and numerous sectors. One of the most affected sectors is the electricity sector, which already deals with challenges caused by decarbonization and the integration of low-carbon technologies. Newly caused challenges are especially important for Distribution System Operators (DSOs) since they are responsible for the planning and operation of distribution networks and for resolving the problems caused by the change of end-users’ habits. To identify and visualize pandemic-induced changes, an integrated geographic information system (GIS)-based tool is developed and presented in this paper. After identifying errors in GIS and end-users’ consumption data and preprocessing them, pandapower and the developed harmonic calculation extension are used for the analysis of different power quality (PQ) indicators in low- voltage (LV) distribution networks. As a final step of the developed tool, the impact of COVID-19 on PQ indicators is visualized using GIS.
