Performance analysis of paralleled VSC-HVDC systems
2016 International Conference on Microelectronics, Computing and Communications (MicroCom), 2016This paper presents a detailed study of the VSC-HVDC system along with the related cases of paralleling two similar VSC-HVDC systems. A basic VSC-HVDC system is designed with controllers on either side of the system. The system is further expanded by connecting a similar VSC-HVDC system in parallel for enhancing the reliability.

DC line protection for VSC-HVDC system
2012 IEEE International Conference on Power Electronics, Drives and Energy Systems (PEDES), 2012Voltage source converters based HVDC (VSC-HVDC) systems involving overhead transmission lines are prone to severe over-currents and over-voltages during dc line faults. This necessitates the operation of the system with some kind of protective devices to overcome the effects of dc line faults.

Fault Current Limiters for VSC-HVDC systems
10th IET International Conference on AC and DC Power Transmission (ACDC 2012), 2012Fault Current Limiters (FCL) limit fault current levels to a more manageable level, this way it becomes possible to increase the transmission ratings of an electrical system, without changing the equipment. Thus, the existing equipment is able to handle the new currents and protect properly the system.

Overview on VSC-HVDC Systems Based on PV
2018 IEEE International Power Electronics and Application Conference and Exposition (PEAC), 2018As a result of the rapid development of DC charging and the extensive use of electronic devices, the number of DC loads has increased dramatically. Loads have the characteristics of AC and DC coexist. At the same time, there are many distributed power sources in microgrids, such as PV, wind power generation, and so on.
