Parametrierung einer kontinuierlichen DC-Spannungsregelcharakteristik für vermaschte HGÜ-Netze

Abstract

The energy turnaround caused a lot of challenges for the power system as well in the distribution level as in the transmission level. For the transmission level significant distances between areas of high renewable generation, storage capacities and centers of load require a bulk power transmission. As the existing transmission system is not designed for such tasks, a suitable solution is a meshed HVDC grid spanning the existing AC grid. Most state of the art methodologies for controlling DC node voltages can provoke DC oscillations due to their points of discontinuity. This paper proposed a new continuous local control characteristic and presents a methodology for its parameterization according to available AC balancing control capabilities.
