A Comprehensive VSG-based Onshore FRT Control Strategy for OWFs with VSC-MT-HVDC Transmission

This paper proposes a communication-free control strategy at the offshore wind farm (OWF) level to enhance onshore fault ride-through (FRT) grid code compliance of the voltage source converter (VSC)-based multi-terminal high voltage direct current (MT-HVDC) grid. In this proposal, the emerging virtu...
