This paper proposes a framework to integrate high-voltage (HV) sub-transmission grids into extra-high voltage (EHV) grid models to address the decentralization of power injection due to renewable energy expansion. Using real German open data, it quantifies the impact of HV disaggregation on national and cross-border power flows, and introduces an OPF model incorporating topological actions for congestion management. The model is validated on the German grid.

📄 Abstract（原文）
The energy transition entails a considerable increase in renewable energy sources, leading to a gradual decentralization of power injection across the grid. This evolution increases the operational importance of sub-transmission grids, also referred to as high-voltage (HV) grids, across Europe. Consequently, we propose to integrate specific HV grid areas among extra-high voltage (EHV) grid models, in order to include their interactions for national or international power flow studies. A framework is developped to quantify the impact of a local HV disaggregation among an EHV grid model at regional and national scale, as well as on cross-border exchanges capacity. However, HV units are not operated at fixed topology, system operators can apply topological actions to solve congestions. We've developed a model that enhance the usual DC OPF formulation with a representation of HV 1-move topological actions to solve congestions in HV and in EHV, at low complexity cost. The disaggregation is illustrated on the Schleswig-Holstein HV area among a real German EHV model. The OPF model, already introduced in a previous work on test grids, is demonstrated on the German real grid here, its validity for managing congestions in HV is attested, and its sensitivity is checked with a scenarisation.
