Synchronverter-Based Emulation and Control of HVDC Transmission [PDF]
IEEE Transactions on Power Systems, 2016 This paper presents a new control strategy for high voltage direct current (HVDC) transmission based on the synchronverter concept: the sending-end rectifier controls emulate a synchronous motor (SM), and the receiving end inverter emulates a synchronous generator (SG). The two converters connected with a DC line provide what is called a synchronverter
