Abstract

A DC grid based on multi-terminal voltage-source converter is a newly emerging technology, which is particularly suitable for the connection of offshore wind farms. Multi-terminal DC grids will be the key technology for the European offshore ‘Super Grid’. In the project, DC power flow, DC relaying protection, steady state operation, dynamic stability, fault-ride through capability, and impacts of DC grids on the operation of AC grids and power market were studied. Systematic comparison of DC grid topologies and stability control strategies was carried out, and DC grids for offshore wind power transmission and onshore AC grid interconnection were investigated. Operation and control were evaluated using various simulation platforms and experimental test rigs. The outcomes of the project are expected to contribute to integrating offshore wind power into the onshore AC grids in European countries and for the European Super Grid.
