A core objective of the PROMOTioN project is the investigation and demonstration of operation and control of HVDC networks as well as their interaction with offshore wind power plants. While previous work packages of the project, i.e. WP2, WP3 and WP4, focused on simulation-based investigations regarding the challenges associated with the control and protection of future MTDC networks and the connected offshore wind power plants, WP16 continuous their analysis using a laboratory-scaled MTDC demonstrator in a power-hardware-in-the-loop environment.
