Computational Platform to Assess DER Hosting Capacity in Real MV-LV Networks: The Case of Osorno and Valdivia in Chile

To technically inform policymakers about the potential of Chilean distribution networks to accommodate distributed generation, this work presents a computational platform developed for the first Industrial Research Chair between CENTRA at Universidad Adolfo Ibáñez and ACESOL. The platform enables automated modeling of integrated real MV-LV distribution networks, ensuring electrical connectivity and data completeness, particularly developed and tested for the distribution network database of Chile's Superintendency of Electricity and Fuels. The platform also proposes a clustering tool for allocating real load profiles, minimizing differences against aggregated power records at the head of the modeled MV feeder. The platform is used to assess the hosting capacity for residential PV systems in real MV-LV feeders from Valdivia and Osorno in Chile, demonstrating its capabilities and functionalities, but also quantifying the potential for integrating large amounts of distributed generation in the south of Chile. and the technical barriers that limit them.
