Applicability of the publicly available open_eGo dataset for network security analyses on the 110 kV distribution grid level

Abstract

The confidentiality of electrical network models owned by grid operators motivated the development of publicly available models and datasets in recent years. A use case specific validation of these models is necessary to assess the significance of simulation results. In this paper, the applicability of the open_eGo model for static power flow analyzes on the 110 kV distribution grid level is evaluated. Based on a preventive security constrained optimal power flow, the annual amount of distributed generation curtailment is derived. Additionally, the aggregated reactive power demand of the 110 kV network is analyzed. Results of the open_eGo model are compared to the proprietary grid operator model of the same region. The simulation results indicate that further improvements are made by considering the non n-1 secure grid connection of generation units on the 110 kV level. Furthermore, the capability of the open_eGo model to accurately represent the aggregated reactive power demand of the 110 kV distribution network is demonstrated.
