Abstract
This paper reviews ongoing planning for power-electronic-dominated power systems and for the technological implementation of multi-vendor multi-terminal HVDC transmission systems in hybrid AC/DC structures in Germany and Europe. Existing system needs and the possibilities to achieve embedded multi-terminal HVDC overlay grids are described. Additional research activities on technical topics in order to answer open research questions for the secure and reliable operation of power-electronic-dominated power systems are highlighted. The need for European cooperation including TSO, vendors and research institutes is described. As an example, simulation results are given and discussed with respect to multi-terminal HVDC planning options.
