The result of the survey will be used as the first step to introduce the possible communication solutions such as network and data transfer protocols in order to ensure the reliable data delivery in operation of multi-national DC grids.en1474-667020136 PART 15863CommunicationControl and protectionDC gridsVSC-HVDCConference Paper10.3182/20130522-3-RO-4035.00018Other
