System Operation Concept for the Curative Use of Thermal Reserves of HVDC Cables

In the light of the energy transition, high voltage direct current (HVDC) cables become increasingly important for energy transmission. Based on the previously unused thermal reserves of the cables, this work proposes a system operation concept for utilising them within curative system operation. To find an analytical solution to describe the heating process, simplified cable modelling with thermal networks is evaluated. The system operation concept is completed by defining requirements towards a model of the information and communication structure for hybrid power systems. Finally, the structure of this holistic approach is presented.
