Multiterminal-HVDC scaled platform for offshore wind transmission systems emulation

This paper presents a Multiterminal VSC-HVDC (Voltage Sources Converter, High Voltage Direct Current) emulation platform. Design details of the scaled platform are discussed. A DC grid droop-based voltage control method designed following Lyapunov control theory has been adopted. In addition, operational points of the Multiterminal HVDC grid are described. The emulation platform have been tested under wind power change and power converter disconnection scenarios. The emulation results has been verified by means of simulations.
