| Abstract |
The aim of reaching a climate-neutral electric power supply requires a massive integration of renewable energy sources into the main power grid. Multi-terminal HVDC interconnectors provide the capability to integrate largescale offshore wind energy into the main grid and secure at the same time the required interconnection capacity between various countries. Thus, multi-terminal HVDC networks for integration of offshore wind energy are currently pursued by the industry. This paper aims to offer guidance on finding the most suitable strategy for a shared dissipation of the excess energy in case of faults on the onshore ac side of the HVDC converters. For this different energy dissipation strategies are presented and discussed. Simulation results using PSCAD EMTDC areused to highlight the advantages and disadvantages of the different strategies. |
