Estimating network topology and hosting capacity: a multi-level approach

The widespread adoption of electric vehicles (EVs) and photovoltaic (PV) systems, driven by global governmental incentives, is posing significant challenges for distribution system operators (DSOs). To maintain power quality, DSOs must estimate the Hosting Capacity (HC) of their networks for these technologies and strategically plan future investments. However, this task is particularly complex due to the uncertainties involved, as well as the limited availability and quality of data at the distribution level. To address this challenge, this paper introduces an overview of a three-level architecture developed for low voltage (LV) distribution networks. The architecture estimates network topology, constructs an equivalent circuit, and calculates HC using limited static data, thereby enabling optimized investment planning and efficient network management.
