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.
